JOHN HANCOCK FUNDS
A Global Investment Management Firm
101 Huntington Avenue
Boston, Massachusetts 02199-7603

                                March 22, 1996

                            TAX-EXEMPT INCOME FUND

Dear Fellow Shareholder:

As you may know, the John Hancock family of funds has expanded in size with the
addition of the former Transamerica Funds. This presents an opportunity to
combine the money management efforts serving your investment with those of a
similar mutual fund. For this reason, we are proposing a merger of your fund,
John Hancock Tax-Exempt Income Fund, into the John Hancock Tax-Free Bond Fund.

YOUR BOARD OF TRUSTEES BELIEVES THAT THIS MERGER IS APPROPRIATE GIVEN THAT BOTH
FUNDS PURSUE A SIMILAR INVESTMENT OBJECTIVE.

Please take the time to read the enclosed materials and cast your vote on the
enclosed proxy card. Please vote promptly. It is extremely important, no matter
how many shares you own.

Comparative performance information, investment objectives and policies are
described at length for both funds in the enclosed Proxy Statement. We believe
that this merger will benefit you in two ways:

1.     LOWER FUND EXPENSES. Your Trustees firmly believe that combining these
two funds many benefit shareholders by allowing the Fund to capitalize on
expected economies of scale in investment research, operations and other
important areas. By creating a larger combined fund, the merger may lead to
reduced expenses and, ultimately, lower costs for you.

2.     INCREASED INVESTMENT DIVERSIFICATION. By combining both funds' assets
into a single portfolio, the Tax-Free Bond Fund will be able to achieve
greater diversification.

YOUR VOTE IS IMPORTANT!

At a special meeting of shareholders to be held on May 2, 1996 at 9:00 a.m., you
will be asked to approve the merger of the Tax-Exempt Income Fund into the
Tax-Free Bond Fund. Your Board of Trustees has unanimously approved the merger.

We urge you to exercise your right as a shareholder and to vote by completing,
signing and returning the enclosed proxy ballot form to us immediately. Your
prompt response will help avoid the necessity for additional mailings at your
Fund's expense. For your convenience, we have provided a postage-paid envelope.

If you have questions, please call our Financial Advisor or John Hancock Funds
Customer Service Representative at 1-800-225-5291, Monday through Friday
between 8:00 a.m. and 8:00 p.m. Eastern time. Thank you for your prompt
attention to these important matters.

                                             Sincerely,



                                             Edward J. Boudreau, Jr.

                           ______________________

        This Proxy Statement and Prospectus sets forth the information you

Tax-Exempt Income Fund ("Tax-Exempt Income Fund") into John Hancock Tax-Free
Bond Fund ("Tax-Free Bond Fund").  Please read it carefully and retain it for
future reference.  

        This Proxy Statement and Prospectus includes the Prospectus of
Tax-Free Bond Fund for Class A and Class B shares, dated May 1, 1995 as
supplemented January 15, 1996 (EXHIBIT A attached).  Information about
Tax-Exempt Income Fund's shares is incorporated by reference from the
Tax-Exempt Income Fund Prospectus which is available at no charge upon request
to Tax-Exempt Income Fund at 1-800-225-5291.

to this Proxy Statement and Prospectus, and containing additional information
about each of Tax-Free Bond Fund and Tax-Exempt Income Fund, including
historical financial statements, is on file with the Securities and Exchange
Commission ("SEC").  It is available from Tax-Free Bond Fund upon telephone
request and at no charge at the toll-free number stated above.  The Statement
of Additional Information is incorporated by reference into this Prospectus.

        This Proxy Statement and Prospectus relates to Class A and Class B
shares of beneficial interest, par value of $0.01 per share (collectively, the
"Tax-Free Bond Fund Shares"), of Tax-Free Bond Fund which will be issued in

__________________

        The Tax-Free Bond Fund Class A Shares issued to Tax-Exempt Income Fund
for distribution to Tax-Exempt Income Fund's Class A shareholders will have an
aggregate net asset value equal to the aggregate net asset value of Tax-Exempt
Income Fund's Class A shares.  The Tax-Free Bond Fund Class B Shares issued to
Tax-Exempt Income Fund for distribution to Tax-Exempt Income Fund's Class B
shareholders will have an aggregate net asset value equal to the aggregate net
asset value of Tax-Exempt Income Fund's Class B Shares.  The asset values of
Tax-Exempt Income Fund and Tax-Free Bond Fund will be determined at the close
of business (4:00 p.m. Eastern Time) on the Closing Date (as defined below) for
purposes of the proposed reorganization.

        Following the receipt of Tax-Free Bond Fund Shares (1) Tax-Exempt
Income Fund will be liquidated, (2) the Tax-Free Bond Fund Shares will be
distributed to Tax-Exempt Income Fund's shareholders pro rata in exchange for
their shares of Tax-Exempt Income Fund and (3) Tax-Exempt Income Fund will be
terminated.  Consequently, Class A Tax-Exempt Income Fund shareholders will
become Class A shareholders of Tax-Free Bond Fund, and Class B Tax-Exempt
Income Fund shareholders will become Class B shareholders of Tax-Free Bond
Fund.  These transactions are collectively referred to in this Proxy Statement
and Prospectus as the "Reorganization."  The Reorganization is being structured
as a tax-free reorganization so that, in the opinion of tax counsel, no gain or
loss will be recognized by Tax-Free Bond Fund, Tax-Exempt Income Fund or the
shareholders of Tax-Exempt Income Fund.  The terms and conditions of the
Reorganization are more fully described in this Proxy Statement and Prospectus,
and in the Agreement and Plan of Reorganization that is attached as EXHIBIT B. 

        Tax-Free Bond Fund is a diversified open-end management investment
company organized as a Massachusetts business trust in 1989.  Tax-Free Bond
Fund seeks to obtain as high a level of interest income exempt from federal
income taxes as is consistent with preservation of capital.  Tax-Free Bond Fund
seeks to obtain this objective by investing primarily in municipal obligations,
including bonds, notes and commercial paper, the interest on which is exempt
from federal income taxes.

        The principal place of business of both Tax-Free Bond Fund and
Tax-Exempt Income Fund is at 101 Huntington Avenue, Boston, Massachusetts
02199.  Their toll-free telephone number is 1-800-225-5291.  

        The date of this Proxy Statement and Prospectus is March 18, 1996.

entire Proxy Statement and Prospectus carefully.

REASONS FOR THE PROPOSED REORGANIZATION

     Tax-Exempt Income Fund's Board of Trustees has determined that the proposed
Reorganization is in the best interests of Tax-Exempt Income Fund and its
shareholders. In making this determination, the Trustees considered several
relevant factors, including (i) the fact that Tax-Exempt Income Fund
shareholders will be subject to lower Rule 12b-1 fees from the Closing until
December 23, 1996 or later, (ii) the fact that the Adviser has agreed to reduce
the management fee rate applicable to Tax-Free Bond Fund to the same rate
applicable to Tax-Exempt Income Fund if the shareholders of Tax-Exempt Income
Fund approve the Reorganization, (iii) the fact that the investment objectives
and policies of the Funds are substantially similar, (iv) the likelihood that
the Reorganization will result in improved economies of scale over time and a
corresponding decrease in the total expenses currently borne by Tax-Exempt
Income Fund's shareholders, and (v) the fact that combining the Funds' assets
into a single portfolio will enable Tax-Free Bond Fund to achieve greater
diversification than either Fund is now able to achieve. Tax-Exempt Income
Fund's Board of Trustees believes that the Tax-Free Bond Fund shares received in
the Reorganization will

                                      -2-
<PAGE>   12

provide existing Tax-Exempt Income Fund shareholders with substantially the same
investment advantages that they currently enjoy at a comparable level of risk. 
For a more detailed discussion of the reasons for the proposed Reorganization, 
see "Proposal to Approve the Agreement and Plan of Reorganization -- Reasons for
the Proposed Reorganization."

  *   The amount of the 12b-1 fee used to cover service expenses will be up to
      0.25% of the Fund's average net assets attributable to Class A and Class B
      shares, respectively, and any remaining portion (up to 0.75% with respect
      to Class B shares) will be used to cover distribution expenses.

 **   Other expenses include transfer agent, legal, audit, custody and other expenses.

        If the Reorganization is consummated, the actual total operating
expenses of Class A and Class B shares of Tax-Free Bond Fund may vary from the
pro forma operating expenses indicated above due to changes in the net asset
values of Tax-Exempt Income Fund and/or Tax-Free Bond Fund between December 31,
1995 and the Closing Date (defined below).

EXAMPLE

         The following example illustrates the expenses you would pay on a
$1,000 investment under the existing fees for Class A and Class B shares of each
of Tax-Exempt Income Fund and Tax-Free Bond Fund and under the pro forma fees if
the Reorganization had occurred on December 31, 1995. The example assumes (1) a
5% annual return and (2) redemption at the end of each time period.

you understand the various costs and expenses of investing in each of the Funds
and what the costs would be had the Reorganization already occurred. The example

or of Tax-Free Bond Fund after the Reorganization. Actual expenses may vary from
year to year and may be higher or lower than those shown above.

FORM OF ORGANIZATION

     Tax-Exempt Income Fund is a Massachusetts business trust organized in
1976. Tax-Free Bond Fund is a Massachusetts business trust organized in 1989.
Both Funds have authorized and outstanding Class A and Class B shares. After the
Reorganization, Tax-Exempt Income Fund's Class A and Class B shareholders will
become Class A and Class B shareholders, respectively, of Tax-Free Bond Fund and
therefore will become subject to Tax-Free Bond

                                      -12-
<PAGE>   22
        
Fund's Declaration of Trust ("Declaration of Trust"). Although there
are some differences between the provisions applicable to each Fund, the only
material differences in shareholder rights are as follows: (i) the Trustees
of Tax-Exempt Income Fund have a greater ability to amend the Fund's
Declaration of Trust without shareholder approval than do the Trustees of
Tax-Free Bond Fund, although the Trustees in both cases are subject to similar
limitations, and (ii) Tax-Exempt Income Fund's Declaration of Trust requires the
affirmative vote of a higher percentage of shareholders to approve a merger,
consolidation or sale of all or substantially all of the assets of the Fund or
to approve the termination of the Fund than does the Declaration of Trust of
Tax-Free Bond Fund.

     Each share of a class of each Fund represents an equal proportionate
interest in the assets belonging to that Fund. The shares of each Fund's
classes represent an interest in the same portfolio of investments of that Fund
that are allocated to that class. Except as stated below, each Fund's classes
have equal rights as to voting, redemption, dividends and liquidation. Each
class bears different distribution and transfer agent fees and may bear other
expenses properly attributable to that class. Shareholders of each Fund's
classes have exclusive voting rights with respect to the Rule 12b-1
distribution plan relating to their respective class of shares.

SALES CHARGES AND DISTRIBUTION AND SERVICES FEES

     Sales Charges. Both Funds impose an initial sales charge on Class A shares
as described above in the table under the caption "The Funds' Expenses." An
initial sales charge does not apply to Class A shares acquired through the
reinvestment of dividends from net investment income or capital gain
distributions.

     Tax-Free Bond Fund Class A Shares acquired by Tax-Exempt Income Fund's
Class A shareholders pursuant to the Reorganization will not be subject to any
initial sales charge or contingent deferred sales charge ("CDSC") at the time of
the Reorganization but will remain subject to any applicable CDSC upon
redemption of those shares.

Tax-Free Bond Fund and Tax-Exempt Income Fund do not impose an initial sales
charge on Class B shares. However, Class B shares redeemed within six years of
purchase will be subject to a CDSC at the rates set forth below. This CDSC will
be assessed on an amount equal to the lesser of the current market value or the
original purchase cost of the Class B shares being redeemed. Accordingly, Class
B shareholders will not be assessed a CDSC on an increase in account value
above the initial purchase price, including shares derived from reinvested
dividends. The amount of the CDSC, if any, will vary depending on the number of
years from the time the Class B shares were purchased until the time they are
redeemed, as follows:

</TABLE>

     Class B shares of Tax-Free Bond Fund acquired by Tax-Exempt Income Fund's
Class B shareholders pursuant to the Reorganization will not be subject to any
CDSC at the time of the Reorganization, but will remain subject to any CDSC
applicable upon redemption of these shares. For purposes of computing the CDSC
payable upon redemption of Class B shares of Tax-Free Bond Fund acquired
pursuant to the Reorganization and the schedule for automatic conversion of
Class B shares into Class A shares, the holding period of the Tax-Exempt Income
Fund Class B shares will be added to that of the Tax-Free Bond Fund Class B
shares acquired in the Reorganization.

     Distribution and Service Fees.  Both Funds have adopted distribution plans
pursuant to Rule 12b-1 under the Investment Company Act. Under these plans, each
Fund may pay fees to John Hancock Funds, Inc. ("John Hancock Funds") to
reimburse distribution and service expenses incurred in connection with the
Funds' Class A shares. With respect to Tax-Exempt Income Fund Class A shares,
these fees are payable at an annual rate of up to 0.30% of the average daily net
assets of the Fund attributable to Class A shares. With respect to Tax-Free Bond
Fund Class A shares, these fees are payable at an annual rate of up to 0.15% of
the average daily net assets of the Fund attributable to Class A shares. Of the
fee payable by each Fund, up to 0.25% and 0.15%, respectively, of the net assets
of Tax-Exempt Income Fund and Tax-Free Bond Fund attributable to Class A shares
may be used for service expenses and any remainder for distribution expenses.
The fee with respect to Tax-Free Bond Fund Class A shares will increase to 0.25%
on or after December 23, 1996 if the shareholders of Tax-Free Bond Fund approve
the increase at their June 1996 special meeting of shareholders.

     In addition, under the plans, each Fund may pay fees to John Hancock Funds
to reimburse it for distribution and service expenses incurred in connection
with Class B shares. With respect to Tax-Exempt Income Fund's Class B shares,
these fees are payable at an annual rate of up to 1.00% of the average daily net
assets of the Fund attributable to Class B shares. With respect to Tax-Free
Bond Fund Class B shares, these fees are also payable at an annual rate of up to
1.00% of the average daily net assets of the 


                                      -14-
<PAGE>   24

Fund attributable to Class B shares; however, the Fund and John Hancock
Funds have agreed to limit the payment of expenses pursuant to the Tax-Free Bond
Fund's Class B plan to 0.90%. Of the fee payable by each Fund, up to 0.25% of
the net assets of each Fund attributable to Class B shares may be used for
service expenses and the remainder for distribution expenses. The agreement with
John Hancock Funds to limit the payment of Class B Rule 12b-1 fees to 0.90% will
terminate on or after December 23, 1996, after which the fee with respect to
Tax-Free Bond Fund Class B shares will increase to 1.00%.

PURCHASES AND EXCHANGES

     Shares of each Fund may be purchased through certain broker-dealers and
through John Hancock Funds at the public offering price, which is based on the
next determined net asset value per share, plus any applicable sales charge. The
minimum initial investment in shares of each Fund is $1,000 ($250 for group
investments and, with respect to Tax-Free Bond Fund, retirement plans). In
anticipation of the Reorganization, after the Record Date, no new accounts may
be opened in Tax-Exempt Income Fund. Existing shareholders of Tax-Exempt Income
Fund may continue to acquire shares of the Fund after the Record Date by direct
purchase, through a monthly automatic accumulation plan or through the
reinvestment of dividends and distributions.

     Shareholders of each Fund may exchange their shares at net asset value for
shares of the same class, if applicable, of other John Hancock funds. For this
purpose, the shares of John Hancock funds with only one class of shares are
treated as Class A shares whether or not they have been so designated. Shares of
any fund acquired by exchange that are subject to a CDSC will incur the CDSC
upon redemption. The rate of this charge will be the rate in effect for the
exchanged shares at the time of the exchange (except that exchanges into John
Hancock Short-Term Strategic Income Fund, John Hancock Limited Term Government
Fund and John Hancock Intermediate Maturity Government Fund will be subject to
the initial fund's CDSC). The exchange privilege is available only in states
where the exchange can be made legally.

     During the fiscal year ended December 31, 1995, Tax-Exempt Income Fund paid
investment management fees of $2,683,990 to the Adviser.

        Tax-Free Bond Fund pays management fees to the Adviser equal to 0.55%
of the Fund's average daily net asset value. During the fiscal year ended
December 31, 1995, Tax-Free Bond Fund paid investment management fees of
$1,048,120 to the Adviser.

DISTRIBUTION PROCEDURES

     It is the policy of both Funds to declare dividends daily and to pay
dividends monthly from net investment income. Each Fund also distributes
annually all of its other taxable income, including any net short-term and
long-term capital gains it has realized. Tax-Exempt Income Fund will make,
immediately prior to the Closing Date (as defined below), a distribution of any
net income and net realized capital gains it has not yet distributed.

REINVESTMENT OPTIONS

     Unless an election is made to receive cash, the shareholders of both Funds
automatically reinvest all of their respective dividends and capital gain
distributions in additional shares of the same class of the same Fund. These
reinvestments are made at the net asset value per share and are not subject to
any sales charge.

REDEMPTION PROCEDURES

     Shares of both Funds may be redeemed on any business day at a price equal
to the net asset value of the shares next determined after receipt of a
redemption request in good order, less any applicable CDSC. Alternatively,
shareholders of both Funds may sell their shares through securities dealers, who
may charge a fee. Redemptions and repurchases of Class B shares and certain
Class A shares of each Fund are subject to the applicable CDSC, if any. Class A
and Class B shares of Tax-Exempt Income Fund may be redeemed up to and including
the Closing Date (as defined below).

REORGANIZATION

     Effect of the Reorganization.  Pursuant to the terms of the Agreement, the
proposed Reorganization will consist of the acquisition by Tax-Free Bond Fund of
all the assets of Tax-Exempt Income Fund in exchange solely for (i) the
assumption by Tax-Free Bond Fund of all the liabilities of Tax-Exempt Income
Fund and (ii) the issuance of Tax-Free Bond Fund Class A and Class B Shares
equal to the value of these assets, less the amount of these liabilities, to
Tax-Exempt Income Fund. As part of the liquidation process, Tax-Exempt Income
Fund will immediately distribute to its shareholders these Tax-Free Bond Fund
Shares in 

                                      -16-
<PAGE>   26

exchange for their shares of Tax-Exempt Income Fund. Consequently,
Class A shareholders of Tax-Exempt Income Fund will become Class A shareholders
of Tax-Free Bond Fund and Class B shareholders of Tax-Exempt Income Fund will
become Class B shareholders of Tax-Free Bond Fund. After completion of the
Reorganization, the existence of Tax-Exempt Income Fund will be terminated.

     The Reorganization will become effective as of 5:00 p.m. on the closing
date, scheduled for May 3, 1996, or another date on or before December 31, 1996
as authorized representatives of the Funds may agree (the "Closing Date"). The
Tax-Free Bond Fund Class A shares issued to Tax-Exempt Income Fund for
distribution to Tax-Exempt Income Fund's Class A shareholders will have an
aggregate net asset value equal to the aggregate net asset value of Tax-Exempt
Income Fund's Class A shares. Similarly, the Tax-Free Bond Fund Class B shares
issued to Tax-Exempt Income Fund for distribution to Tax-Exempt Income Fund's
Class B shareholders will have an aggregate net asset value equal to the
aggregate net asset value of Tax-Exempt Income Fund's Class B shares. For
purposes of the Reorganization, the Funds' respective asset values will be
determined as of the close of business (4:00 p.m. Eastern Time) on the Closing
Date.

     The Board of Trustees of Tax-Exempt Income Fund, including the trustees
who are not "interested persons" of either Fund or the Adviser (the
"Independent Trustees"), approved the Reorganization, and determined that it
was in the best interests of Tax-Exempt Income Fund and that the interests of
Tax-Exempt Income Fund's shareholders would not be diluted as a result of the
Reorganization. Similarly, the Board of Trustees of Tax-Free Bond Fund,
including the Trustees not affiliated with either Fund or the Adviser, approved
the Reorganization, and determined that it was in the best interests of
Tax-Free Bond Fund and that the interests of Tax-Free Bond Fund's shareholders
would not be diluted as a result of the Reorganization.

TAX CONSIDERATIONS

     The consummation of the Reorganization is subject to the receipt of an
opinion of Hale and Dorr, counsel to the Funds, satisfactory to each Fund, which
will provide generally (as more specifically set forth in the Agreement) that
with respect to the transfers and exchanges comprising the Reorganization:

     (a) The acquisition by Tax-Free Bond Fund of all of the assets of
Tax-Exempt Income Fund will constitute a "reorganization" within the meaning of
Section 368(a) of the Code, and Tax-Exempt Income Fund and Tax-Free Bond Fund
will each be "a party to a reorganization" within the meaning of Section 368(b)
of the Code;


                                      -17-
<PAGE>   27

     (b) no gain or loss will be recognized by Tax-Exempt Income Fund upon (i)
the transfer of all of its assets to Tax-Free Bond Fund and (ii) the
distribution by Tax-Exempt Income Fund of these Tax-Free Bond Fund Shares to the
shareholders of Tax-Exempt Income Fund;

     (c) no gain or loss will be recognized by Tax-Free Bond Fund upon the
receipt of Tax-Exempt Income Fund's assets;

     (d) the basis of the assets of Tax-Exempt Income Fund acquired by Tax-Free
Bond Fund will remain the same as immediately prior to the transfer;

     (e) the tax holding period of the assets of Tax-Exempt Income Fund in the
hands of Tax-Free Bond Fund will include Tax-Exempt Income Fund's tax holding
period for those assets;

     (f) the shareholders of Tax-Exempt Income Fund will not recognize gain or
loss upon the exchange of their shares of Tax-Exempt Income Fund solely for
Tax-Free Bond Fund Shares in the Reorganization;

     (g) the basis of the Tax-Free Bond Fund Shares received by Tax-Exempt
Income Fund shareholders in the Reorganization will be the same; and

     (h) the tax holding period of the Tax-Free Bond Fund Shares received by
Tax-Exempt Income Fund shareholders will include the tax holding period of
Tax-Exempt Income Fund shares that were held as capital assets.

THE MEETING

     Time, Place and Date.  The Meeting will be held on Thursday, May 2, 1996,
at 101 Huntington Avenue, Boston, Massachusetts 02199, at 9:00 a.m., Boston 
time.

RECORD DATE

     The Record Date for determining shareholders entitled to notice of and to
vote at the Meeting is March 6, 1996.

VOTE REQUIRED

     Approval of the Agreement by the shareholders of Tax-Exempt Income Fund
requires the affirmative vote of a majority of the shares of Tax-Exempt Income
Fund outstanding and entitled to vote. For this purpose, a majority of the
outstanding shares of Tax-Exempt Income Fund means the vote of the lesser of (i)
67% or more of the shares present at the Meeting, if the holders of more than
50% of the shares of the Fund are present or represented by proxy, 


                                      -18-

<PAGE>   28

or (ii) more than 50% of the outstanding shares of the Fund ("Majority  
Shareholder Vote"). The Reorganization does not require the approval of
Tax-Free Bond Fund's shareholders. See "Proposal to Approve the Agreement and
Plan of Reorganization--Voting Rights and Required Vote."

                     RISK FACTORS AND SPECIAL CONSIDERATIONS

     Please see the Tax-Free Bond Fund Prospectus and the Tax-Exempt Income Fund
Prospectus for a more complete description of each Fund's investment objectives
and policies, as well as their risk factors. In deciding whether to approve the
Reorganization, you should consider the similarities and differences between the
Funds' investment objectives, policies and risk factors.

     The investment objectives and policies of the Funds are substantially
similar. For this reason, the risks associated with an investment in the Funds
are substantially similar. Each Fund invests primarily in municipal bonds and
other securities whose interest is exempt from Federal income taxes. Under
normal circumstances, at least 80% of Tax-Free Bond Fund's total assets will be
invested in these securities and 85% of Tax-Exempt Income Fund's total assets
will be invested in these securities.

     Tax-Exempt Income Fund may invest up to 35% of its total assets in
municipal securities and Tax-Free Bond Fund may invest up to 35% of its total   
assets in municipal bonds and notes rated B or better by an NRSRO or, if not
rated, determined by the Adviser to be of comparable quality. These investments
are considered speculative and are commonly called "junk bonds." While
generally providing greater income than investments in higher quality
securities, these investments involve greater risk of principal and income
loss, including the possibility of default. These investments may have greater
price volatility, especially during periods of economic uncertainty or changes.
Bonds rated B are currently meeting debt service requirements but provide a
limited margin of safety and are vulnerable to default in the event of adverse
business, financial or economic conditions. In addition, the market for these
bonds may be less liquid than the market for higher rated securities.
Therefore, the Adviser's judgment at times plays a greater role in the
performance and valuation of investments in these investments.

     Up to 20% of Tax-Free Bond Fund's total assets may be invested in
securities that are taxable, while only up to 15% of Tax-Exempt Income Fund's
total assets may be so invested.


                                      -19-
<PAGE>   29

     There is no limit on Tax-Free Bond Fund's average portfolio maturity.
Tax-Exempt Income Fund's average portfolio maturity ranges from 20 to 25 years.
Generally, the longer the average portfolio maturity, the greater will be the
impact of interest rate fluctuations on the value of that Fund's assets and net
asset value per share.

     Tax-Free Bond Fund may buy and sell covered call and put options on debt
securities in which it may invest, and on indices composed of debt securities in
which it may invest. The Fund may also sell straddles, which are combinations of
put and call options on the same security. The Fund may make these investments
to hedge its exposure to changing interest rates and security prices. Options
are derivative instruments and may involve certain risks. If the Adviser applies
a hedge at an inappropriate time or judges market conditions incorrectly,
options may lower the Fund's return. If option prices are not correctly
correlated with the Fund's other investments or if the Fund is not able to close
out its positions, the Fund may experience losses. Also, options do not pay
interest but may produce taxable gains or losses. Tax-Exempt Income Fund may not
invest in these options or straddles.

     The presence at the meeting of a majority of Tax-Exempt Income Fund's
outstanding shares entitled to vote will be considered a quorum for
the transaction of business. A Tax-Exempt Income Fund shareholder executing and
returning a proxy has the power to revoke it at any time before it is
exercised, by filing a written notice of revocation with Tax-Exempt Income
Fund's transfer agent, Investor Services, P.O. Box 9116, Boston, Massachusetts
02205-9116, or by returning a duly executed proxy with a later date before the
time of the Meeting. Any shareholder who has executed a proxy but is present at
the Meeting and wishes to vote in person may revoke his or her proxy by
notifying the Secretary of Tax-Exempt Income Fund (without complying with any
formalities) at any time before it is voted. Presence at the Meeting alone will
not serve to revoke a previously executed and returned proxy.

     If a quorum is not present in person or by proxy at the time any session of
the Meeting is called to order, the persons named as proxies may vote those
proxies that have been received to adjourn the Meeting to a later date. If a
quorum is present but there are not sufficient votes in favor of the Proposal,
the persons named as proxies may propose one or more adjournments of the Meeting
to permit further solicitation of proxies with respect to the Proposal. Any
adjournment will require the affirmative vote of a majority of the shares of
Tax-Exempt Income Fund, represented in person or by proxy, at the session of the
Meeting to be adjourned. If an adjournment of the Meeting is proposed because
there are not sufficient votes in favor of the Reorganization, the persons named
as proxies will vote those proxies in favor of the Reorganization in favor of
adjournment, and will vote those proxies against the Reorganization against
adjournment.

     In addition to the solicitation of proxies by mail or in person, Tax-Exempt
Income Fund may also arrange to have votes recorded by telephone by officers and
employees of the Fund or by personnel of the Adviser or Investor Services. The
telephone voting procedure is designed to authenticate a shareholder's identity,
to allow a shareholder to authorize the voting of shares in accordance with the
shareholder's instructions and to confirm that the voting instructions have been
properly recorded. If these procedures were subject to a successful legal
challenge, these telephone votes would not be counted at the Meeting. The Fund
has not sought to obtain an opinion of counsel on this matter and is unaware of
any challenge at this time. A shareholder will be called on a recorded line at
the telephone number in the Fund's account records and will be asked the
shareholder's Social Security number or other identifying information. The
shareholder will then be given an opportunity to authorize proxies to vote his



                                      -21-
<PAGE>   31

or her shares at the Meeting in accordance with the shareholder's instructions.
To ensure that the shareholder's instructions have been recorded correctly, the
shareholder will also receive a confirmation of the voting instructions in the
mail. A special toll-free number will be available in case the voting
information contained in the confirmation is incorrect. If the shareholder
decides after voting by telephone to attend the Meeting, the shareholder can
revoke the proxy at that time and vote the shares at the Meeting.

                       PROPOSAL TO APPROVE THE AGREEMENT
                           AND PLAN OF REORGANIZATION

GENERAL

     The shareholders of Tax-Exempt Income Fund are being asked to approve the
Agreement, a copy which is attached as EXHIBIT B. The Reorganization will
consist of: (a) the transfer of all of Tax-Exempt Income Fund's assets to
Tax-Free Bond Fund, in exchange solely for the issuance of Tax-Free Bond Fund
Shares to Tax-Exempt Income Fund and the assumption of Tax-Exempt Income Fund's
liabilities by Tax-Free Bond Fund, (b) the subsequent distribution by Tax-Exempt
Income Fund, as part of its liquidation, of the Tax-Free Bond Fund Shares to
Tax-Exempt Income Fund's shareholders and (c) the termination of Tax-Exempt
Income Fund's existence. The Tax-Free Bond Fund Class A shares issued upon the
consummation of the Reorganization will have an aggregate net asset value equal
to the aggregate net asset value of the assets attributable to Tax-Exempt Income
Fund's Class A shares, less liabilities attributable to Tax-Exempt Income Fund's
Class A shares. Similarly, the Tax-Free Bond Fund Class B shares issued upon the
consummation of the Reorganization will have an aggregate net asset value equal
to the aggregate net asset value of the assets attributable to Tax-Exempt Income
Fund's Class B shares, less liabilities attributable to Tax-Exempt Income Fund's
Class B shares. As noted above, the asset values of Tax-Exempt Income Fund and
Tax-Free Bond Fund will be determined at the close of business (4:00 p.m.
Eastern Time) on the Closing Date for purposes of the Reorganization. See
"Description of Agreement" below.

     Pursuant to the Agreement, Tax-Exempt Income Fund will liquidate and
distribute the Tax-Free Bond Fund Shares received, as described above, pro rata
to the shareholders of record of each class determined as of the close of
regular trading on the New York Stock Exchange on the Closing Date. The result
of the transfer of assets will be that Tax-Free Bond Fund will add to its
portfolio the net assets of Tax-Exempt Income Fund. Class A 


                                      -23-
<PAGE>   33
shareholders of Tax-Exempt Income Fund will become Class A shareholders of Tax-
Free Bond Fund, and Class B shareholders of Tax-Exempt Income Fund will become
Class B shareholders of Tax-Free Bond Fund.

     The Agreement and the Reorganization were approved by the Board of Trustees
of Tax-Exempt Income Fund at a meeting held on December 11, 1995. The Agreement
and the Reorganization were approved by the Board of Trustees of Tax-Free Bond
Fund at a meeting held on November 28, 1995. In connection with their approval
of the Reorganization, the Board of Trustees considered several matters
described in greater detail below under the caption "Reasons for the Proposed
Reorganization."

REASONS FOR THE PROPOSED REORGANIZATION

     The Board of Trustees of Tax-Exempt Income Fund believes that the proposed
Reorganization will be advantageous to the shareholders of Tax-Exempt Income
Fund in several respects. The Board of Trustees considered the following
matters, among others, in approving the Proposal.

     First, the Board of Trustees believes that it is not advantageous to
operate and market Tax-Exempt Income Fund separately from Tax-Free Bond Fund
because their investment objectives and policies are substantially similar. By
being offered simultaneously, each Fund hinders the other Fund's potential for
asset growth. 

     Second, the Board of Trustees considered that shareholders may be better
served by a fund offering greater diversification. To the extent that the Funds'
assets are combined into a single portfolio and a larger asset base is created
as a result of the Reorganization, greater diversification of Tax-Free Bond
Fund's investment portfolio can be achieved than is currently possible in either
Fund. Greater diversification is expected to be beneficial to shareholders of
both Funds because it may reduce the negative effect which the adverse
performance of any one security may have on the performance of the entire
portfolio.

Third, the Board of Trustees considered the fact that Tax-Free Bond Fund is
subject to a higher management fee rate than Tax-Exempt Income Fund. The Board  
of Trustees also considered, however, the proposal by the Adviser to reduce its
management fee rate for the Tax-Free Bond Fund if the Reorganization is
approved by Tax-Exempt Income Fund's shareholders to the same rate currently
applicable to Tax-Exempt Income Fund. The Board of Trustees believes that the
decrease in 

                                      -24-
<PAGE>   34

management fee rate will not result in Tax-Free Bond Fund receiving lower
quality of services from the Adviser. The Adviser believes that the merger may
result in a lower overall management fee rate for the current fiscal year if
the combined assets of Tax-Free Bond Fund remain in excess of $500,000,000.

        Fourth, the Board of Trustees considered the fact that after the
Reorganization the assets of Tax-Free Bond Fund attributable to Tax-Exempt      
Income Fund will be subject to lower Rule 12b-1 fees. The shareholders of
Tax-Free Bond Fund will, at their special meeting in June 1996, consider a
proposal by John Hancock Funds to increase the Fund's Class A Rule 12b-1 fee
from its current rate of 0.15% of average daily net assets of the Fund
attributable to the Fund's Class A share to 0.25%, yet this increased fee
remains lower than Tax-Exempt Income Fund's current Class A Rule 12b-1 fee of
0.30%. Furthermore, the increase will not take effect until December 23, 1996
or later. In addition, the Board of Trustees of Tax-Exempt Income Fund
considered John Hancock Funds' removal of the expense limitation limiting the
Class B Rule 12b-1 fee to 0.90% of average net assets of the Fund attributable
to Class B shares. As a result, the Class B Rule 12b-1 fee will increase to
1.00%, which is the same Class B Rule 12b-1 fee currently paid by Tax-Exempt
Income Fund. The Board of Trustees further considered that the Class B Rule
12b-1 fee adjustment will not occur until December 23, 1996 or later.

     Fifth, the Board of Trustees believes that the Tax-Free Bond Fund Shares
received in the Reorganization will provide existing Tax-Exempt Income Fund
shareholders with substantially the same investment advantages that they
currently enjoy at a comparable level of risk. The Board of Trustees also
considered the performance history of each Fund.

        Sixth, a combined fund offers economies of scale that should have a
positive effect on the expenses currently borne by Tax-Exempt Income Fund, and  
hence, indirectly, its shareholders. Both Funds incur substantial costs for
accounting, legal, insurance, and custodial and administrative services. The
Board of Trustees expects that the Reorganization may result in a decrease over
time in the expenses currently borne indirectly by Tax-Exempt Income Fund's
shareholders. See expense information in "Summary--the Funds' Expenses."

     The Board of Trustees considered the fact that, from the perspective of
Tax-Free Bond Fund, the Reorganization presents an excellent opportunity to
acquire assets without the obligation to pay commissions or other similar costs
that are normally associated with the purchase of securities. This opportunity
provides an economic benefit to Tax-Free Bond Fund and its shareholders.

     


                                      -25-
<PAGE>   35
     The Board of Trustees also considered the fact that the Adviser and John
Hancock Funds will receive certain benefits from the Reorganization. The
consolidated portfolio management effort might result in time savings for the
Adviser and the preparation of fewer prospectuses, reports and regulatory
filings. The Trustees, however, believe that this consideration will not amount
to a significant economic benefit.

CAPITAL LOSS CARRYOVERS

     As of December 31, 1995, Tax-Exempt Income Fund had capital loss
carryovers, as determined for federal income tax purposes, in the aggregate   
amount of approximately $8,110,320, of which $2,374,664 expires on December 31,
2002, and $5,735,656 expires on December 31, 2003. If the Reorganization does
not occur, Tax-Exempt Income Fund may use these capital loss carryovers to
offset any net capital gain, which would reduce the amount of net capital gain
Tax-Exempt Income Fund would be required to distribute to its shareholders in
order to avoid fund level income and/or excise taxes on undistributed capital
gain.

     If the Reorganization is consummated, Tax-Free Bond Fund will succeed to
and take into account Tax-Exempt Income Fund's capital loss carryovers and will
be able to use such carryovers, along with any carryovers it may have, to offset
any net capital gain, subject to certain limitations under the Code that may be
applicable because of the Reorganization and certain other changes in the past
or future share ownership of Tax-Free Bond Fund. These limitations could result
in the expiration of all or portions of such carryovers before they are fully
used.

UNREIMBURSED DISTRIBUTION AND SHAREHOLDER SERVICE EXPENSES

     The Board of Trustees has determined that, if the Reorganization is
consummated, distribution and shareholder service expenses incurred in
connection with shares of Tax-Exempt Income Fund, and not reimbursed under
Tax-Exempt Income Fund's Rule 12b-1 Plans or through CDSCs, will be reimbursable
expenses under Tax-Free Bond Fund's Rule 12b-1 Plans (the "assumption").
However, the maximum aggregate amounts payable during any fiscal year under
Tax-Free Bond Fund's Rule 12b-1 Plans (0.25% of average daily net assets
attributable to Class A shares and 1.00% of average daily net assets
attributable to Class B shares) will not be affected by the assumption.

     With respect to Tax-Free Bond Fund's Class A and Class B shares, the
percentage of net assets on a pro forma combined basis that the unreimbursed
expenses represent will decrease as a result of the Reorganization and the
assumption. As of December 31, 1995 the unreimbursed distribution and
shareholder service expenses of 


                                      -26-
<PAGE>   36
Tax-Free Bond Fund attributable to Class A and Class B shares were $105,329
(.09%) of Tax-Free Bond Fund's net assets attributable to Class A shares and 
$3,009,952 (3.96%) of Tax-Free Bond Fund's net assets attributable to Class B 
shares, respectively. As of the same date, the unreimbursed distribution and 
shareholder service expenses of Tax-Exempt Income Fund attributable to Class A
and Class B shares were $495,815 (.01%) attributable to Class A shares and 
$298,337 (3.52%) of Tax-Exempt Income Fund's net assets attributable to Class B
shares, respectively.

     After the Reorganization on a pro forma combined basis, the
unreimbursed distribution and shareholder service expenses of Tax-Free Bond
Fund attributable to Class A and Class B shares will be $601,144 (0.01% of
Tax- Free Bond Fund's pro forma net assets attributable to Class A shares) and
3,299,889 (3.92% of Tax-Free Bond Fund's pro forma net assets attributable to
Class B shares), respectively.

     The assumption will have no immediate effect upon the payments made under
Tax-Free Bond Fund's Rule 12b-1 Plans. While John Hancock Funds hopes to recover
unreimbursed distribution and shareholder service expenses over an extended
period of time, Tax-Free Bond Fund is not obligated to assure that these amounts
are recouped by John Hancock Funds.

     Unreimbursed distribution and shareholder service expenses do not currently
appear as an expense or liability in the financial statements of either Fund,
nor will they appear in the financial statements of Tax-Free Bond Fund after the
Reorganization until paid or accrued. Even in the event of termination or
noncontinuance of Tax-Free Bond Fund's Rule 12b-1 Plans, Tax-Free Bond Fund is
not legally committed, and is not required to commit, to the payment of any
unreimbursed distribution and shareholder service expenses. For this reason,
unreimbursed expenses do not enter into the calculation of a Fund's net asset
value or the formula for calculating Rule 12b-1 payments. The staff of the SEC
has not approved or disapproved the treatment of the unreimbursed distribution
and shareholder service expenses described in this Proxy Statement

BOARDS' EVALUATION AND RECOMMENDATION

     On the basis of the factors described above and other factors, the Board of
Trustees, including a majority of the Independent Trustees, determined that the
Reorganization is in the best interests of Tax-Exempt Income Fund and that the
interests of Tax-Exempt Income Fund's shareholders will not be diluted as a
result of the Reorganization. On the same basis, the Board of Trustees of
Tax-Free Bond Fund, including a majority of the Independent Trustees determined


                                      -27-
<PAGE>   37

that the Reorganization is in the best interests of Tax-Free Bond Fund and that
the interests of Tax-Free Bond Fund's shareholders will not be diluted as a
result of the Reorganization.

     THE TRUSTEES OF JOHN HANCOCK TAX-EXEMPT INCOME FUND RECOMMEND THAT THE
SHAREHOLDERS OF JOHN HANCOCK TAX-EXEMPT INCOME FUND VOTE FOR THE PROPOSAL TO
APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

DESCRIPTION OF AGREEMENT

     The following description of the Agreement is a summary, does not purport
to be complete, and is subject in all respects to the provisions of the
Agreement, and is qualified in its entirety by reference to the Agreement. A
copy of the Agreement is attached to this Proxy Statement and Prospectus as
EXHIBIT B and should be read in its entirety. Paragraph references are to
appropriate provisions of the Agreement.

     Method of Carrying Out Reorganization.  If Tax-Exempt Income Fund
shareholders approve the Agreement, the Reorganization will be consummated
promptly after the various conditions to the obligations of each of the parties
are satisfied (see Agreement, paragraphs 6 through 8). The Reorganization will
be completed on the Closing Date.

     On the Closing Date, Tax-Exempt Income Fund will transfer all of its assets
to Tax-Free Bond Fund in exchange for Tax-Free Bond Fund Shares with an
aggregate net asset value equal to the value of the assets delivered, less the
liabilities of Tax-Exempt Income Fund assumed, as of the close of business on
the Closing Date (see Agreement, paragraphs 1 and 2).

     The value of Tax-Exempt Income Fund's assets and Tax-Free Bond Fund's
net asset values per Class A share and per Class B share will be determined
according to the valuation procedures set forth in Tax-Exempt Income Fund's 
Prospectus and Statement of Additional Information and in the Tax-Free Bond
Fund Prospectus, respectively (see "Share Price" in the Tax-Free Bond Fund
Prospectus). 

     Surrender of Share Certificates.  Tax-Exempt Income Fund shareholders whose
shares are represented by one or more share certificates should, prior to the
Closing Date, either surrender their certificates to Tax-Exempt Income Fund or
deliver to Tax-Exempt Income Fund an affidavit with respect to lost
certificates, in the form and accompanied by the surety bonds that Tax-Exempt
Income Fund may require (collectively, an "Affidavit"). On the Closing Date, all
certificates which have not been surrendered will be deemed to be cancelled,
will no longer evidence ownership of Tax-Exempt Income Fund's shares and will 
evidence ownership of


                                      -28-
<PAGE>   38

Tax-Free Bond Fund Shares. Shareholders may not redeem or transfer Tax-Free 
Bond Fund Shares received in the Reorganization until they have surrendered 
their Tax-Exempt Income Fund share certificates or delivered an Affidavit 
relating to them. Tax-Free Bond Fund will not issue share certificates in the
Reorganization.

     Conditions Precedent to Closing.  The obligation of Tax-Exempt Income Fund
to consummate the Reorganization is subject to the satisfaction of certain
conditions precedent, including the performance by Tax-Free Bond Fund of all
acts and undertakings required under the Agreement and the receipt of all
consents, orders and permits necessary to consummate the Reorganization (see
Agreement, paragraphs 6 through 8).

     The obligation of Tax-Free Bond Fund to consummate the Reorganization is
subject to the satisfaction of certain conditions precedent, including
Tax-Exempt Income Fund's performance of all acts and undertakings to be
performed under the Agreement, the receipt of certain documents and financial
statements from Tax-Exempt Income Fund, and the receipt of all consents, orders
and permits necessary to consummate the Reorganization (see Agreement,
paragraphs 6 through 8).

     The obligations of both parties are subject to the receipt of approval and
authorization of the Agreement by the requisite vote of the holders of the
outstanding shares of beneficial interest of Tax-Exempt Income Fund in
accordance with the provisions of the Fund's Declaration of Trust, as amended,
and By-Laws and the receipt of a favorable opinion of Hale and Dorr as to the
federal income tax consequences of the Reorganization. (See Agreement, paragraph
8).

     Termination of Agreement.  The Agreement may be terminated, whether or not
approval of Tax-Exempt Income Fund's shareholders has been obtained, by mutual
agreement of the parties. In addition, either party may terminate its
obligations under the Agreement at or prior to the Closing Date, because of a
material breach by the other party of any representations, warranties or
agreements contained in the Agreement, or if a condition precedent in the
Agreement has not been met.

     Expenses of the Reorganization.  Tax-Free Bond Fund and Tax-Exempt Income
Fund will each be responsible for its own expenses incurred in connection with
entering into and carrying out the provisions of the Agreement, whether or not
the Reorganization is consummated.

     Tax Considerations.  The consummation of the Reorganization is subject to
the receipt of a favorable opinion of Hale and Dorr, counsel to the Funds,
satisfactory to Tax-Exempt Income Fund and Tax-Free Bond Fund and described
above under the caption "Summary--Reorganization-Tax Considerations."

                                      -29-

<PAGE>   39

VOTING RIGHTS AND REQUIRED VOTE

     Each Tax-Exempt Income Fund share is entitled to one vote. Approval of the
Proposal requires an affirmative Majority Shareholder Vote. 

     Shares of beneficial interest of Tax-Exempt Income Fund represented in
person or by proxy, including shares which abstain or do not vote with respect
to the Proposal, will be counted for purposes of determining whether a quorum is
present at the Meeting. Accordingly, an abstention from voting has the same
effect as a vote against the Proposal. However, if a broker or nominee holding
shares in "street name" indicates on the proxy card that it does not have
discretionary authority to vote on the Proposal, those shares will not be
considered as present and entitled to vote with respect to the Proposal.
Accordingly, a "broker non-vote" has no effect on the voting in determining
whether the Proposal has been adopted pursuant to clause (i) in the immediately
preceding paragraph, provided that the holders of more than 50% of the
outstanding shares (excluding the "broker non-votes") are present or
represented. However, for purposes of determining whether the Agreement has been
adopted pursuant to clause (ii) in the immediately preceding paragraph, a
"broker non-vote" has the same effect as a vote against the Proposal because
shares represented by a "broker non-vote" are considered to be outstanding
shares.

     If the requisite approval of shareholders is not obtained, Tax-Exempt
Income Fund will continue to engage in business as a registered open-end,
management investment company and the Board of Trustees will consider what
further action may be appropriate.

                                CAPITALIZATION
                                 (UNAUDITED)

     The following table sets forth the capitalization of each Fund as of
December 31, 1995, and the pro forma combined capitalization of both Funds as
if the Reorganization had occurred on such date. The table reflects pro forma
exchange ratios of approximately 1.0314 Class A Tax-Free Bond Fund Shares being
issued for each Class A share of Tax-Exempt Income Fund and approximately
1.0312 Class B Tax-Free Bond Fund Shares being issued for each Class B share of
Tax-Exempt Income Fund. If the Reorganization is consummated, the actual
exchange ratios on the Closing Date may vary from the exchange ratios indicated
due to changes in the market value of the portfolio securities of both Tax-Free
Bond Fund and Tax-Exempt Income Fund between December 31, 1995 and the 


                                      -30-

Closing Date, changes in the amount of undistributed net investment
income and  net realized capital gains of Tax-Free Bond Fund and Tax-Exempt
Income Fund  during that period resulting from income and distributions, and
changes in the accrued liabilities of Tax Free Bond Fund and Tax-Exempt Income
Fund during the same period.

</TABLE>

        If the Reorganization had taken place on December 31, 1995, Tax-Exempt  
Income Fund would have received 46,474,198 Class A shares and 810,743 Class B
shares of Tax-Free Bond Fund which would have been available for distribution to
shareholders of the applicable class of Tax-Exempt Income Fund. No assurance can
be given as to the number of Class A shares or Class B shares of Tax-Free Bond
Fund that will be received by Tax-Exempt Income Fund on the Closing Date. The
foregoing is merely an example of what Tax-Exempt Income Fund would have
received and distributed had the Reorganization been consummated on December 31,

     The average annual total return at public offering price on Tax-Free Bond
Fund's Class A shares for the one-year, five-year and life-of-class periods
ended December 31, 1995 was 14.79%, 8.84%, and 8.39%, respectively. The average
annual total return at public offering price on Tax-Free Bond Fund's Class B
shares for the one-year and life-of-class periods ended December 31, 1995 was
14.42% and 7.24%, respectively. Total returns on Class B shares reflect the
applicable contingent deferred sales charge.

     The average annual total return of each class of the Funds is determined by
multiplying a hypothetical initial investment of $1,000 in a class by the
average annual compound rate of return (including capital
appreciation/depreciation, and dividends and distributions paid and reinvested)
attributable to that class for the stated period and annualizing the result.

     The table below indicates the total return (capital changes plus
reinvestment of all dividends and distributions) on a hypothetical investment
of $1,000 in each class of each Fund covering the indicated periods ending
December 31, 1995. The data below represent historical performance which should
not be considered indicative of future performance of either Fund. Each Fund's
performance and net asset value will fluctuate such that shares, when redeemed,
may be worth more or less than their original cost.

                 JOHN HANCOCK TAX-FREE BOND FUND, MAY 1, 1995

                 SUPPLEMENT TO CLASS A AND CLASS B PROSPECTUS


The "INVESTMENT OBJECTIVE AND POLICIES" section is amended as follows:

The Fund may invest up to 35% of its assets in municipal bonds and notes
rated, at time of purchase, Ba, B by Moody's Investors Services, Inc., BB, B by
Standard and Poor's Rating Group or Fitch or, if not rated, determined by the
John Hancock Advisers, Inc. (the "Adviser") to be of comparable credit  
quality. These bonds are considered speculative and are generally referred to
as junk bonds. While generally providing greater income than investments and in
higher quality securities, these bonds involve greater risk of principal and
income loss, including the possibility of default. These bonds may have greater 
price volatility, especially during periods of economic uncertainty or change.
Bonds rated B are currently meeting debt services requirements but provide a
limited margin of safety and are vulnerable to default in the event of adverse
business, financial or economic conditions. In addition, the market for these
bonds may be less liquid than the market for higher rated securities.
Therefore, the Adviser's judgment at times play a greater role in the
performance and valuation of the Fund's investments in these bonds.

"THE FUND'S EXPENSES" section is amended as follows:

The Trustees of the Fund have voted to recommend that the Class A shareholders
of the Fund approve an increase in the Rule 12b-1 fee for Class A shares of the
Fund from 0.15% of average daily net assets to 0.25% of average daily net
assets effective at the end of 1996. Also at the end of 1996, the Distributor
will remove its Rule 12b-1 fee reduction on Class B shares Rule 12b-1 plan so   
that the fee increases from 0.90% of average daily net assets to 1.00% of
average daily net assets.

November 28, 1995

The "ORGANIZATION AND MANAGEMENT OF THE FUND" section is amended as follows:

Thomas C. Goggins is Senior Vice President of the Adviser and portfolio manager
of the Fund. Mr. Goggins heads up John Hancock's team of municipal managers and
analysts. he joined the Adviser in 1995. Previously to that date, Mr. Goggins
was a municipal bond portfolio manager at Putnam Investments and Transamerica
Investment Services, Inc.

INVESTMENT OBJECTIVE AND POLICIES
The Fund's investment objective is to obtain as high a level of interest income
exempt from federal income taxes as is consistent with preservation of capital.
The Fund seeks to achieve its objective by investing primarily in municipal
bonds, notes and commercial paper, the interest on which is exempt from federal
income taxes ("Municipal Obligations"). Municipal Obligations include debt
obligations issued by or on behalf of states, territories and possessions of the
United States; the District of Columbia; and the political subdivisions,
agencies or instrumentalities thereof.
 
- -------------------------------------------------------------------------------
                   THE FUND SEEKS TO PROVIDE INCOME EXEMPT
                   FROM FEDERAL INCOME TAX.
- -------------------------------------------------------------------------------
 
Under normal market conditions, at least 80% of the Fund's total assets will be
invested in Municipal Obligations. At least 65% of the Fund's assets will
normally be invested in municipal bonds. Pending the investment of Fund assets
in Municipal Obligations and to meet redemption requests, the Fund may invest up
to 20% of its total assets in private activity bonds (the interest on which may
be treated as a tax preference item under the Federal alternative minimum tax)
and in certain taxable money market securities, including: obligations issued or
guaranteed by the U.S. government, its agencies, instrumentalities or
authorities; corporate debt securities; commercial paper; certificates of
deposit of domestic banks with assets of $1 billion or more; and repurchase
agreements secured by U.S. Government securities.
 
When John Hancock Advisers, Inc. (the "Adviser") determines that unfavorable
investment conditions warrant a temporary defensive position, the Fund may
invest more than 20% of its assets in taxable money market securities rated in
the three highest ratings as determined by Moody's Investors Services, Inc.
("Moody's"), Standard & Poor's Ratings Group ("S&P") or Fitch Investors Service
("Fitch") or, if unrated, determined by the Adviser to be of comparable quality.
See the Statement of Additional Information for a description of those ratings.
 
Municipal bonds generally are classified as either general obligation bonds or
revenue bonds. General obligation bonds are backed by the credit of an issuer
having taxing power and are payable from the issuer's general unrestricted
revenues. Their payment may depend on an appropriation of the issuer's
legislative body. Revenue bonds, by contrast, are payable only from the revenues
derived from a particular project, facility or a specific revenue source. They
are not generally payable from the unrestricted revenues of the issuer.
Municipal notes include tax anticipation notes, bond anticipation notes, revenue
anticipation notes and project notes. Municipal commercial paper obligations are
unsecured promissory notes issued by municipalities to meet short-term credit
needs.
 
- -------------------------------------------------------------------------------
                   THE FUND'S INVESTMENT IN MUNICIPAL
                   OBLIGATIONS INCLUDES MUNICIPAL BONDS,
                   MUNICIPAL NOTES AND MUNICIPAL COMMERCIAL
                   PAPER.
- -------------------------------------------------------------------------------
 
At the time of purchase, municipal bonds including private activity bonds must
be rated at least investment grade, i.e., Baa by Moody's, BBB by S&P or Fitch
or, if not rated, determined by the Adviser to be of comparable credit quality.
Municipal notes must be rated at least Aa by Moody's or AA by S&P or Fitch or,
if not rated, determined by the Adviser to be of comparable credit quality.
Municipal commercial paper must be rated at least Prime-2 by Moody's or A-1+ by
S&P. The Fund may retain Municipal Obligations whose ratings are downgraded
below permissible ratings until the Adviser determines that disposing of such
Obligations is in the best interest of the Fund. Municipal bonds rated BBB or
Baa are considered to have some speculative characteristics and can pose special
risks involving the ability of the issuer to make payment of principal and
interest to a greater extent than higher rated securities. See Appendix A to the
Statement of Additional Information for additional discussion of the ratings
assigned to Municipal Obligations.
 
- -------------------------------------------------------------------------------
                   THE FUND INVESTS IN MUNICIPAL OBLIGATIONS.
- -------------------------------------------------------------------------------
 
                                        4
<PAGE>   53
 
The Adviser will purchase municipal bonds rated BBB or Baa where, based upon
price, yield and its assessment of quality, investment in such bonds is
determined to be consistent with the Fund's objective of preservation of
capital. The Adviser will evaluate and monitor the quality of all investments,
including bonds rated BBB or Baa, and will dispose of such bonds necessary to
assure that the Fund's overall portfolio is constituted in manner consistent
with the goal of preservation of capital. To the extent that the Fund's
investments in municipal bonds rated BBB or Baa includes obligations believed to
be consistent with the goal of preserving capital, such bonds may not provide
yields as high as those of other obligations having such ratings and the
differential in yields between such bonds and obligations with higher quality
ratings may not be as significant as might otherwise be generally available.
 
Because there is no restriction on the maturities of the Municipal Obligations
in which the Fund may invest, the Fund's average portfolio maturity is not
subject to any limit. Generally, the longer the average portfolio maturity, the
greater will be the impact of fluctuations in interest rates on the values of
the Fund's assets and on the net asset value per share.
 
- -------------------------------------------------------------------------------
                   THERE IS NO RESTRICTION ON THE MATURITIES
                   OF THE FUND'S MUNICIPAL OBLIGATIONS.
- -------------------------------------------------------------------------------
 
The Fund may write (sell) covered call and put options on debt securities in
which it may invest and on indices composed of debt securities in which it may
invest. The Fund may purchase call and put options on these securities and
indices. The Fund may also write straddles, which are combinations of put and
call options on the same security. The Fund may buy and sell interest rate and
municipal bond index futures contracts and options on such futures contracts to
hedge against changes in securities prices and interest rates.
 
- -------------------------------------------------------------------------------
                   THE FUND MAY EMPLOY CERTAIN INVESTMENT
                   STRATEGIES TO HELP ACHIEVE ITS INVESTMENT
                   OBJECTIVE.
- -------------------------------------------------------------------------------
 
The Fund may invest in variable rate and floating rate obligations, including
inverse floating rate obligations, on which the interest rate is adjusted at
predesignated periodic intervals or when there is a change in the market rate of
interest on which the interest rate payable on the obligation is met is based.
 
Options, futures contracts and variable and floating rate instruments are
generally considered to be "derivative" instruments because they derive their
value from the performance of an underlying asset, index or other economic
benchmark. See "Investments, Techniques and Risk Factors" for additional
discussion of derivative instruments.
 
The Fund will not concentrate in any one industry (governmental issuers are not
considered to be part of any "industry"). While the Fund may invest more than
25% of its total assets in industrial development or pollution control bonds, it
may
 
                                        5
<PAGE>   54
 
not invest more than 25% of its assets in industrial development or pollution
control bonds which are dependent, directly or indirectly, on the revenues or
credit of private entities in any one industry.
 
The Fund may purchase tax exempt participation interests and municipal lease
obligations, may lend its portfolio securities, enter into repurchase
agreements, purchase restricted and illiquid securities and purchase securities
on a when-issued or forward commitment basis.
 
See "Investments, Techniques and Risk Factors" for more information about the
Fund's investments.
 
The Fund has adopted certain investment restrictions which are enumerated in
detail in the Statement of Additional Information where they are classified as
fundamental or nonfundamental. Those restrictions designated as fundamental may
not be changed without shareholder approval. The Fund's investment objective and
its policy to invest (under normal market conditions) 80% of its assets in
Municipal Obligations are fundamental and may not be changed without the
approval of the Fund's shareholders. The Fund's other investment policies and
its nonfundamental restrictions, however, may be changed by a vote of the
Trustees without shareholder approval. Notwithstanding the Fund's fundamental
investment restriction prohibiting investments in other investment companies,
the Fund may, pursuant to an order granted by the SEC, invest in other
investment companies in connection with a deferred compensation plan for the
non-interested trustees of the John Hancock Group of Funds. There can be no
assurance that the Fund will achieve its investment objective.
 
- -------------------------------------------------------------------------------
                   THE FUND FOLLOWS CERTAIN POLICIES WHICH
                   MAY HELP TO REDUCE INVESTMENT RISK.
- -------------------------------------------------------------------------------
 
RISK FACTORS.  An investment in the Fund is intended for long-term investors who
can accept the risks associated with investing primarily in fixed-income
securities. The Fund's investments will be subject to market fluctuation and
other risks inherent in all securities. The yield, return and price volatility
of the Fund depend on the type and quality of its investments as well as market
and other factors. In addition, the Fund's potential investments and management
techniques may entail specific risks. For additional information about risks
associated with an investment in the Fund, see "Investments, Techniques and Risk
Factors."
 
The primary consideration in choosing brokerage firms to carry out the Fund's
transactions is execution at the most favorable prices, taking into account the
broker's professional ability and quality service. Consideration may also be
given to the broker's sales of Fund shares. Pursuant to procedures determined by
the Trustees, the Adviser may place securities transactions with brokers
affiliated with the Adviser. The brokers include Tucker Anthony Incorporated,
Sutro and Company, Inc. and John Hancock Distributors, Inc., which are
indirectly owned by the John Hancock Mutual Life Insurance Company (the "Life
Company"), which in turn indirectly owns the Adviser.

distributes shares for all of the John Hancock mutual funds through Selling
Brokers. Certain Fund officers are also officers of the Adviser and John Hancock
Funds.

All investment decisions are made by the Adviser's fixed-income portfolio
management team and no single person is primarily responsible for making
recommendations to the team.
 
In order to avoid any conflict with portfolio trades for the Fund, the Adviser
and the Fund have adopted extensive restrictions on personal securities trading
by personnel of the Adviser and its affiliates. Some of these restrictions are:
preclearance for all personal trades and a ban on the purchase of initial public
offerings, as well as contributions to specified charities of profits on
securities held for less than 91 days. These restrictions are a continuation of
the basic principle that the interests of the Fund and its shareholders come
first.
 
ALTERNATIVE PURCHASE ARRANGEMENTS
You can purchase shares of the Fund at a price equal to their net asset value
per share plus a sales charge. At your election, this charge may be imposed
either at the time of the purchase (see "Initial Sales Charge Alternative,"
Class A shares) or on a contingent deferred basis (the "Contingent Deferred
Sales Charge Alternative," Class B shares). If you do not specify on your
account application the class of shares you are purchasing, it will be assumed
that you are investing in Class A shares.
 
- -------------------------------------------------------------------------------
                   AN ALTERNATIVE PURCHASE PLAN ALLOWS YOU TO
                   CHOOSE THE METHOD OF PAYMENT THAT IS BEST
                   FOR YOU.
- -------------------------------------------------------------------------------
 
CLASS A SHARES.  If you elect to purchase Class A shares, you will incur an
initial sales charge unless the amount of your purchase is $1 million or more.
If you purchase $1 million or more of Class A shares, you will not be subject to
an initial sales charge, but you will incur a sales charge if you redeem your
shares within one year of purchase. Class A shares are subject to ongoing
distribution and service fees at a combined annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A shares. Certain
purchases of Class A shares qualify for reduced initial sales charges. See
"Share Price -- Qualifying for a Reduced Sales Charge."

                   INVESTMENTS IN CLASS A SHARES ARE SUBJECT
                   TO AN INITIAL SALES CHARGE.

<PAGE>   56
 
CLASS B SHARES.  You will not incur a sales charge when you purchase Class B
shares, but the shares are subject to a sales charge if you redeem them within
six years of purchase (the "contingent deferred sales charge" or the "CDSC").
Class B shares are subject to ongoing distribution and service fees at a
combined annual rate of up to 1.00% of the Fund's average daily net assets
attributable to the Class B shares. Investing in Class B shares permits all of
your dollars to work from the time you make your investment, but the higher
ongoing distribution fee will cause these shares to have higher expenses than
those of Class A shares. To the extent that any dividends are paid by the Fund,
these higher expenses will also result in lower dividends than those paid on
Class A shares.
 
- -------------------------------------------------------------------------------
                   INVESTMENTS IN CLASS B SHARES ARE SUBJECT
                   TO A CONTINGENT DEFERRED SALES CHARGE.
- -------------------------------------------------------------------------------
 
Class B shares are not available for fullservice defined contribution plans
administered by Investor Services or the Life Company that had more than 100
eligible employees at the inception of the Fund account.
 
FACTORS TO CONSIDER IN CHOOSING AN ALTERNATIVE.  The alternative purchase
arrangement allows you to choose the most beneficial way to buy shares, given
the amount of your purchase, the length of time you expect to hold your shares
and other circumstances. You should consider whether, during the anticipated
life of your Fund investment, the CDSC and accumulated fees on Class B shares
would be less than the initial sales charge and accumulated fees on Class A
shares purchased at the same time, and to what extent this differential would be
offset by the Class A shares' lower expenses. To help you make this
determination, the table under the caption "Expense Information" on the inside
cover page of this Prospectus shows examples of the charges applicable to each
class of shares. Class A shares will normally be more beneficial if you qualify
for reduced sales charges. See "Share Price--Qualifying for a Reduced Sales
Charge."
 
- -------------------------------------------------------------------------------
                   YOU SHOULD CONSIDER WHICH CLASS OF SHARES
                   WOULD BE MORE BENEFICIAL TO YOU.
- -------------------------------------------------------------------------------
 
Class A shares are subject to lower distribution fees and, accordingly, pay
correspondingly higher dividends per share, to the extent any dividends are
paid. However, because initial sales charges are deducted at the time of
purchase, you would not have all of your funds invested initially and,
therefore, would initially own fewer shares. If you do not qualify for reduced
initial sales charges and expect to maintain your investment for an extended
period of time, you might consider purchasing Class A shares. This is because
the accumulated distribution and service charges on Class B shares may exceed
the initial sales charge and accumulated distribution and service charges on
Class A shares during the life of your investment.
 
Alternatively, you might determine that it is more advantageous to purchase
Class B shares to have all of your funds invested initially. However, you will
be subject to higher distribution and service fees and, for a six-year period, a
CDSC.
 
In the case of Class A shares, the distribution expenses that John Hancock
Funds, Inc. ("John Hancock Funds") incurs in connection with the sale of the
shares will be paid from the proceeds of the initial sales charge and ongoing
distribution and service fees. In the case of Class B shares, the expenses will
be paid from the
 
                                        8
<PAGE>   57
 
proceeds of the ongoing distribution and service fees, as well as from the CDSC
incurred upon redemption within six years of purchase. The purpose and function
of the Class B shares' CDSC and ongoing distribution and service fees are the
same as those of the Class A shares' initial sales charge and ongoing
distribution and service fees. Sales personnel distributing the Fund's shares
may receive different compensation for selling each class of shares.
 
Dividends, if any, on Class A and Class B shares will be calculated in the same
manner, at the same time and on the same day. They also will be in the same
amount, except for differences resulting from each class bearing only its own
distribution and service fees, shareholder meeting expenses and any incremental
transfer agency costs. See "Dividends and Taxes."
 
THE FUND'S EXPENSES
 
For managing its investment and business affairs, the Fund pays a monthly fee to
the Adviser equal to 0.55% of the Fund's average daily net assets. During the
Fund's most recent fiscal year, the advisory fee was 0.44% of the Fund's average
daily net assets. The Adviser has voluntarily and temporarily agreed to continue
to limit the Fund's operating expenses and not to impose its management fee to
the extent necessary to limit the total of the Fund's management fees and
operating expenses (not including fees payable by the Fund under a Rule 12b-1
plan) to .70% of the average net assets attributable to Class A and Class B
shares.
 
The Class A and Class B shareholders have adopted distribution plans (each a
"Plan") pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the
"1940 Act"). Under these Plans, the Fund will pay distribution and service fees
at an aggregate annual rate of up to 0.15% of the Class A shares' average daily
net assets and an aggregate annual rate of 1.00% of the Class B shares' average
daily net assets. John Hancock Funds has temporarily agreed to limit the
distribution and services fees pursuant to the Class B Plan to 0.90% of average
daily net assets. Up to 0.25% for Class B shares and 0.15% for Class A shares is
for service expenses and the remaining amount is for distribution expenses. The
distribution fees will be used to reimburse John Hancock Funds for its
distribution expenses, including but not limited to: (i) initial and ongoing
sales compensation to Selling Brokers and others (including affiliates of John
Hancock Funds) engaged in the sale of Fund shares; (ii) marketing, promotional
and overhead expenses incurred in connection with the distribution of Fund
shares; (iii) unreimbursed distribution expenses under the Fund's prior
distribution plans; (iv) distribution expenses incurred by other investment
companies which sell all or substantially all of its assets to, merge or
otherwise engage in a reorganization transaction with the Fund; and (v) with
respect to Class B shares only, interest expenses on unreimbursed distribution
expenses. The service fees will be used to compensate Selling Brokers for
providing personal and account maintenance services to shareholders.

                   SHAREHOLDER SERVICING.
- -------------------------------------------------------------------------------
 
In the event John Hancock Funds is not fully reimbursed for payments it makes or
expenses it incurs under the Class A Plan, these expenses will not be carried
beyond one year from the date they were incurred. Unreimbursed expenses under
the Class B Plan will be carried forward together with interest on the balance
of
 
                                        9
<PAGE>   58
 
these unreimbursed expenses. For the fiscal year ended December 31, 1994, an
aggregate of $3,316,138 of distribution expenses or 4.72% of the average net
assets of the Fund's Class B shares was not reimbursed or recommended by John
Hancock Funds through receipt of deferred sales charges or Rule 12b-1 fees in
prior periods.
 
Information on the Fund's total expenses is in the Financial Highlights section
of this Prospectus.
 
DIVIDENDS AND TAXES
 
DIVIDENDS.  The Fund generally declares dividends daily and distributes
dividends monthly, representing all or substantially all of its net investment
income. The Fund will distribute net realized long-term and short-term capital
gains, if any, annually before the close of the fiscal year (December 31).
 
- -------------------------------------------------------------------------------
                   YOU SHOULD KEEP YOUR ACCOUNT STATEMENTS
                   RECEIVED BY THE FUND FOR YOUR PERSONAL TAX
                   RECORDS.
- -------------------------------------------------------------------------------
 
Dividends are reinvested in additional shares of your class unless you elect the
option to receive them in cash. If you elect the cash option and the U.S. Postal
Service cannot deliver your checks, your election will be converted to the
reinvestment option. Because of the higher expenses associated with Class B
shares, any dividends on these shares will be lower than those on the Class A
shares. See "Share Price."
 
TAXATION.  The Fund intends to meet certain federal tax requirements so that its
distributions of the tax-exempt interest it earns may be treated as
"exempt-interest dividends," which you are entitled to treat as tax-exempt
interest. That portion of exempt-interest dividends, if any, attributable to
interest on certain tax-exempt obligations that are "private activity bonds" may
increase certain shareholders' alternative minimum tax.
 
Shareholders receiving social security benefits and certain railroad retirement
benefits may be subject to Federal income tax on up to 85 percent of such
benefits as a result of receiving investment income, including tax-exempt income
(such as exempt-interest dividends) and other dividends paid by the Fund. Shares
of the Fund may not be an appropriate investment for persons who are
"substantial users" of facilities financed by industrial development or private
activity bonds, or persons related to "substantial users." Consult your tax
adviser if you think this may apply to you.
 
Dividends from the Fund's net taxable income, if any, including any market
discount included in the Fund's income, and from the Fund's net short-term
capital gains are taxable to you as ordinary income. Dividends from the Fund's
net long-term capital gains are taxable as long-term capital gain. These
dividends are taxable, whether received in cash or reinvested in additional
shares. Certain dividends may be paid by the Fund in January of a given year but
may be treated as if you received them the previous December.
 
The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). As a regulated investment company, the Fund will not be
subject to
 
                                       10
<PAGE>   59
 
Federal income tax on any net investment income or net realized capital gains
distributed to its shareholders within the time period prescribed by the Code.
When you redeem (sell) or exchange shares, you may realize a taxable gain or
loss.
 
On the account application you must certify that your social security or other
tax payer identification number is correct and that you are not subject to
backup withholding of Federal income tax. If you do not provide this information
or are otherwise subject to this withholding, the Fund may be required to
withhold 31% of your taxable dividends, and 31% of the proceeds of redemptions
or exchanges.
 
In addition to Federal taxes, you may be subject to state and local taxes with
respect to your investment in and distributions from the Fund. A state income
(and possibly local income and/or intangible property) tax exemption is
generally available to the extent the Fund's distributions are derived from
interest on (or, in the case of intangibles taxes, the value of its assets is
attributable to) certain U.S. Government obligations and/or tax-exempt municipal
obligations issued by or on behalf of the particular state or a political
subdivision thereof, provided in some states that certain thresholds for
holdings of such obligations and/or reporting requirements are satisfied. You
will receive tax information each year showing the percentage of the Fund's
exempt-interest dividends attributable to each state. You should consult your
tax adviser for specific advice.
 
PERFORMANCE
 
Yield reflects the Fund's rate of income on portfolio investments as a
percentage of its share price. Yield is computed by annualizing the result of
dividing the net investment income per share over a 30 day period by the maximum
offering price per share on the last day of that period. Yield is also
calculated according to accounting methods that are standardized for all stock
and bond funds. Because yield accounting methods differ from the methods used
for other accounting purposes, the fund's yield may not equal the income paid on
shares or the income reported in the Fund's financial statements. The Fund may
also utilize tax equivalent yields of its Class A and Class B shares computed in
the same manner, with adjustment for assumed Federal income tax rates. For a
comparison of yields on municipal securities and taxable securities, see the
Taxable Equivalent Yield Table in Appendix A.
 
- -------------------------------------------------------------------------------
                   THE FUND MAY ADVERTISE ITS YIELD AND TOTAL
                   RETURN.
- -------------------------------------------------------------------------------
 
The Fund's total return shows the overall dollar or percentage change in value
of a hypothetical investment in the Fund, assuming the reinvestment of all
dividends. Cumulative total return shows the Fund's performance over a period of
time. Average annual total return shows the cumulative return divided over the
number of years included in the period. Because average annual total return
tends to smooth out variations in the Fund's performance, you should recognize
that it is not the same as actual year-to-year results.
 
Both total return and yield calculations for Class A shares generally include
the effect of paying the maximum sales charge (except as shown in "The Fund's
Financial Highlights"). Investments at a lower sales charge would result in
higher performance figures. Total return and yield for Class B shares reflects
the
 
                                       11
<PAGE>   60
 
deduction of the applicable CDSC imposed on a redemption of shares held for the
applicable period. All calculations assume that all dividends are reinvested at
net asset value on the reinvestment dates during the periods. Total return and
yield of Class A and Class B shares will be calculated separately and, because
each class is subject to different expenses, the total return may differ with
respect to that class for the same period. The relative performance of the Class
A and Class B shares will be affected by a variety of factors, including the
higher operating expenses attributable to the Class B shares, whether the Fund's
investment performance is better in the earlier or later portions of the period
measured and the level of net assets of the Classes during the period. The Fund
will include the total return of Class A and Class B shares in any advertisement
or promotional materials including Fund performance data. The value of Fund
shares, when redeemed, may be more or less than their original cost. Both yield
and total return are historical calculations, and are not an indication of
future performance. See "Factors to Consider in Choosing an Alternative."

SHARE PRICE
The net asset value per share ("NAV") is the value of one share. The NAV per
share is calculated by dividing the net assets of each class by the number of
outstanding shares of that class. The NAV of each class can differ in value.
Securities in the Fund's portfolio are valued on the basis of market quotations,
valuations provided by independent pricing services or, at fair value as
determined in good faith according to procedures approved by the Trustees.
Short-term debt investments maturing within 60 days are valued at amortized cost
which the Board has determined approximates market value. If quotations are not
readily available, assets are valued by a method that the Trustees believe
accurately reflects fair value.

                   THE OFFERING PRICE OF YOUR SHARES IS THEIR
                   NET ASSET VALUE PLUS A SALES CHARGE, IF
                   APPLICABLE, WHICH WILL VARY WITH THE
                   PURCHASE ALTERNATIVE YOU CHOOSE.

The NAV is calculated once daily as of the close of regular trading on the New
York Stock Exchange (the "Exchange") (generally at 4:00 P.M., New York time) on
each day that the Exchange is open.
 
Shares of the Fund are sold at the offering price based on the NAV computed
after your investment request is received in good order by John Hancock Funds.
If you

buy shares of the Fund through a Selling Broker, the Selling Broker must receive
your investment before the close of regular trading on the Exchange and transmit
it to John Hancock Funds before its close of business to receive that day's
offering price.
 
INITIAL SALES CHARGE ALTERNATIVE -- CLASS A SHARES.  The offering price you pay
for Class A shares of the Fund equals the NAV plus a sales charge as follows:

  (*) Upon notice to Selling Brokers with whom it has sales agreements, John
      Hancock Funds may reallow an amount up to the full applicable sales
      charge. In addition to the reallowance allowed to all selling Brokers,
      John Hancock Funds will pay the following: round trip airfare to a resort
      will be offered to each registered representative of a Selling Broker (if
      the Selling Broker has agreed to participate) who sells certain amounts of
      shares of John Hancock funds. John Hancock Funds will make these incentive
      payments out of its own resources. A Selling Broker to whom substantially
      the entire sales charge is reallowed or who receives these incentives may
      be deemed to be an underwriter under the Securities Act of 1933. Other
      than distribution and service fees, the Fund does not bear distribution
      expenses.
 
 (**) No sales charge is payable at the time of purchase in Class A shares of $1
      million or more, but a CDSC may be imposed in the event of certain
      redemption transactions within one year of purchase.
 
(***) John Hancock Funds may pay a commission and the first year's service fee
      (as described in (+) below) to Selling Brokers who initiate and are
      responsible for purchases of $1 million or more in aggregate as follows: 1
      % on sales to $4,999,999, 0.50% on the next $5 million and 0.25% on
      amounts over $10 million.
 
  (+) At the time of sale, John Hancock Funds pays to Selling Brokers the first
      year's service fee in advance in an amount equal to 0.25% of the net
      assets invested in the Fund at the time of the sale, and thereafter, it
      pays the service fee periodically in arrears in an amount up to 0.25% of
      the Fund's average annual net assets. Selling Brokers receive the fee as
      compensation for providing personal and account maintenance services to
      shareholders.
 
Sales charges ARE NOT APPLIED to any dividends that are reinvested in additional
Class A shares of the Fund.
 
                                       15
<PAGE>   64
 
In addition, John Hancock Funds will pay certain affiliated Selling Brokers at
an annual rate of up to 0.05% of the daily net assets of accounts attributable
to these brokers.
 
Under certain circumstances described below, investors in Class A shares may be
entitled to pay reduced sales charges. See "Qualifying for a Reduced Sales
Charge."
 
CONTINGENT DEFERRED SALES CHARGE -- INVESTMENTS OF $1 MILLION OR MORE IN CLASS A
SHARES. Purchases of $1 million or more of Class A shares will be made at net
asset value with no initial sales charge, but if the shares are redeemed within
12 months after the end of the calendar month in which the purchase was made
(the CDSC period), a CDSC will be imposed. The rate of the CDSC will depend on
the amount invested as follows:

Existing full service clients of the Life Company who were group annuity
contract holders as of September 1, 1994 and participant directed defined
contribution plans with at least 100 eligible employees at the inception of the
Fund Account may purchase Class A shares with no initial sales charge. However,
if the shares are redeemed within 12 months after the end of the calendar year
in which the purchase was made, a CDSC will be imposed at the above rate.
 
The CDSC will be assessed on an amount equal to the lesser of the current market
value or the original purchase cost of the Class A shares that have been
redeemed. Accordingly, no CDSC will be imposed on increases in account value
above the initial purchase price, including any distributions which have been
reinvested in additional Class A shares.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
Therefore, it will be assumed that the redemption is first made from any shares
in your account that are not subject to the CDSC. The CDSC is waived on
redemptions in certain circumstances. See "Waiver of Contingent Deferred Sales
Charge" below.
- -------------------------------------------------------------------------------
                   YOU MAY QUALIFY FOR A
                   REDUCED SALES CHARGE ON
                   YOUR INVESTMENT IN
                   CLASS A SHARES.
- -------------------------------------------------------------------------------
 
QUALIFYING FOR A REDUCED SALES CHARGE.  If you invest more than $100,000 in
Class A shares of the Fund or a combination of funds within the John Hancock
family of funds (except money market funds), you may qualify for a reduced sales
charge on your investments in Class A shares through a LETTER OF INTENTION. You
may also be able to use the ACCUMULATION PRIVILEGE and the COMBINATION PRIVILEGE
to take advantage of the value of your previous investments in Class A shares of
the John Hancock funds in meeting the breakpoints for a reduced sales charge.
For the ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE, the applicable sales
charge will be based on the total of:
 
 
1.  Your current purchase of Class A shares of the Fund.
 
                                       16
<PAGE>   65
 
2.  The net asset value (at the close of business on the previous day) of (a)
    all Class A shares of the Fund you hold, and (b) all Class A shares of any
    other John Hancock funds you hold; and
 
3.  The net asset value of all shares held by another shareholder eligible to
    combine his or her holdings with you into a single "purchase."
 
EXAMPLE:
If you hold Class A shares of a John Hancock fund with a net asset value of
$80,000 and, subsequently, invest $20,000 in Class A shares of the Fund, the
sales charge on this subsequent investment would be 3.75% and not 4.50%. This
rate is the rate that would otherwise be applicable to investments of less than
$100,000. See "Initial Sales Charge alternative -- Class A Shares."
 
If you are in one of the following categories, you may purchase Class A shares
of the Fund without paying a sales charge:
 
- - A Trustee or officer of the Fund; a Director or officer of the Adviser and its
  affiliates or Selling Brokers; employees or sales representatives of any of
  the foregoing; retired officers, employees or Directors of any of the
  foregoing; a member of the immediate family of any of the foregoing; or any
  Fund, pension, profit sharing or other benefit plan for the individuals
  described above.
 
- -------------------------------------------------------------------------------
                   CLASS A SHARES MAY BE AVAILABLE WITHOUT A
                   SALES CHARGE TO CERTAIN INDIVIDUALS AND
                   ORGANIZATIONS.
- -------------------------------------------------------------------------------
 
- - Any state, county, city or any instrumentality, department, authority, or
  agency of these entities that is prohibited by applicable investment laws from
  paying a sales charge or commission when it purchases shares of any registered
  investment management company.*
 
- - A bank, trust company, credit union, savings institution or other types of
  depository institution, its trust departments or common trust funds if it is
  purchasing $1 million or more for non-discretionary customers or accounts.*
 
- - A broker, dealer or registered investment adviser that has entered into an
  agreement with John Hancock Funds providing specifically for the use of Fund
  shares in fee-based investment products made available to their clients.
 
- - A former participant in an employee benefit plan with John Hancock funds, when
  he/she withdraws from his/her plan and transfers any or all of his/her plan
  distributions directly to the Fund.
- ------------------
*For investments made under these provisions, John Hancock Funds may make a
payment out of its own resources to the Selling Broker in an amount not to
exceed 0.25% of the amount invested.
 
Class A shares of the Fund may be purchased without an initial sales charge in
connection with certain liquidation, merger or acquisition transactions
involving other investment companies or personal holding companies.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE -- CLASS B SHARES.  Class B shares
are offered at net asset value per share without a sales charge so that your
entire initial investment will go to work at the time of purchase. However,
Class B shares redeemed within six years of purchase will be subject to a CDSC
at the
 
                                       17
<PAGE>   66
 
rates set forth below. This charge will be assessed on an amount equal to the
lesser of the current market value or the original purchase cost of the shares
being redeemed. Accordingly, you will not be assessed a CDSC on increases in
account value above the initial purchase price, including shares derived from
dividend reinvestment.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
It will be assumed that your redemption comes first from shares you have held
beyond the six-year CDSC redemption period or those you acquired through
reinvestment of dividends and next from the shares you have held the longest
during the six-year period. The CDSC is waived on redemptions in certain
circumstances. See the discussion "Waiver of Contingent Deferred Sales Charges"
below.
 
EXAMPLE:
 
You have purchased 100 shares at $10 per share. The second year after your
purchase, your investment's net asset value per share has increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment. If
you redeem 50 shares at this time, your CDSC will be calculated as follows:
 
<TABLE>
<S>                                                                         <C>
- - Proceeds of 50 shares redeemed at $12 per share                           $  600
- - Minus proceeds of 10 shares not subject to CDSC because they were
  acquired through dividend reinvestment (10 X $12)                           -120
- - Minus appreciation on remaining shares, also not subject to CDSC (40 X
  $2)                                                                         - 80
                                                                            ------
- - Amount subject to CDSC                                                    $  400
</TABLE>
 
Proceeds from the CDSC are paid to John Hancock Funds. John Hancock Funds uses
part of them to defray its expenses related to providing the Fund with
distribution services connected to the sale of Class B shares, such as
compensating Selling Brokers for selling these shares. The combination of the
CDSC and the distribution and service fees makes it possible for the Fund to
sell Class B shares without deducting a sales charge at the time of the
purchase.
 
The amount of the CDSC, if any, will vary depending on the number of years from
the time you purchase your Class B shares until the time you redeem them. Solely
for the purposes of determining the holding period, any payments you make during
the month will be aggregated and deemed to have been made on the last day of the
month.

A commission equal to 3.75% of the amount invested and a first year's service
fee equal to 0.25% of the amount invested are paid to Selling Brokers. The
initial service fee is paid in advance at the time of sale for the provision of
personal and account maintenance services to shareholders during the twelve
months following the sale, and thereafter the service fee is paid in arrears.
 
WAIVER OF CONTINGENT DEFERRED SALES CHARGES.  The CDSC will be waived on
redemptions of Class B shares and of Class A shares that are subject to a CDSC,
unless indicated otherwise, in these circumstances:
 
- - Redemptions of Class B shares made under Systematic Withdrawal Plan (see "How
  to Redeem Shares"), as long as your annual redemptions do not exceed 10% of
  your account value at the time you establish your Systematic Withdrawal Plan
  and 10% of the value of your subsequent investments (less redemptions) in that
  account at the time you notify Investor Services. This waiver does not apply
  to Systematic Withdrawal Plan redemptions of Class A shares that are subject
  to a CDSC.
 
- -------------------------------------------------------------------------------
                   UNDER CERTAIN CIRCUMSTANCES, THE CDSC
                   ON CLASS B AND CERTAIN
                   CLASS A SHARE REDEMPTIONS WILL BE WAIVED.
- -------------------------------------------------------------------------------
 
- - Redemptions made to effect distributions from an Individual Retirement Account
  either before or after age 59 1/2, as long as the distributions are based on
  the life expectancy of the joint-and-last survivor life expectancy of you and
  your beneficiary. These distributions must be free from penalty under the
  Code.
 
- - Redemptions made to effect mandatory distributions under the Code after age
 70 1/2 from a tax-deferred retirement plan.
 
- - Redemptions made to effect distributions to participants or beneficiaries from
  certain employer-sponsored retirement plans including those qualified under
  Section 401(a) of the Code, custodial accounts under Section 403(b)(7) of the
  Code and deferred compensation plans under Section 457 of the Code. The waiver
  also applies to certain returns of excess contributions made to these plans.
  In all cases, the distributions must be free from penalty under the Code.
 
- - Redemptions due to death or disability.
 
- - Redemptions made under the Reinvestment Privilege, as described in "Additional
  Services and Programs" of this Prospectus.
 
- - Redemptions made pursuant to the Fund's right to liquidate your account if you
  have less than $100 invested in the Fund.
 
- -Redemptions made in connection with certain liquidation, merger or acquisition
 transactions involving other investment companies or personal holding
 companies.
 
- -Redemptions from certain IRA and retirement plans that purchased shares prior
 to October 1, 1992.
 
If you qualify for a CDSC waiver under one of these situations, you must notify
Investor Services either directly or through your Selling Broker at the time you
make your redemption. The waiver will be granted once Investor Services has
confirmed that you are entitled to the waiver.

CONVERSION OF CLASS B SHARES.  Your Class B shares and an appropriate portion of
reinvested dividends on those shares will be converted into Class A shares
automatically. This will occur no later than the month following eight years
after the shares were purchased, and will result in lower annual distribution
fees. If you exchanged Class B shares into the Fund from another John Hancock
fund, the calculation will be based on the time you purchased the shares in the
original fund. The Fund has been advised that the conversion of Class B shares
to Class A shares should not be taxable for Federal income tax purposes and
should not change a shareholder's tax basis or tax holding period for the
converted shares.
 
HOW TO REDEEM SHARES
You may redeem all or a portion of your shares on any business day. Your shares
will be redeemed at the next NAV calculated after your redemption request is
received in good order by Investor Services, less any applicable CDSC. The Fund
may hold payment until it is reasonably satisfied that investments recently made
by check or Invest-by-Phone have been collected (which may take up to 10
calendar days).
 
- -------------------------------------------------------------------------------
                   TO ASSURE ACCEPTANCE OF YOUR REDEMPTION
                   REQUEST, PLEASE FOLLOW THESE PROCEDURES.
- -------------------------------------------------------------------------------
 
Once your shares are redeemed, the Fund generally sends you payment on the next
business day. When you redeem your shares, you may realize a taxable gain or
loss depending usually on the difference between what you paid for them and what
you receive for them, subject to certain tax rules. Under unusual circumstances,
the Fund may suspend redemptions or postpone payment for up to seven days or
longer, as permitted by Federal securities laws.

                         Fund, redemption proceeds of $1,000 or more can be wired on
                         the next business day to your designated bank account, and
                         a fee (currently $4.00) will be deducted. You may also use
                         electronic funds transfer to your assigned bank account,
                         and the funds are usually collectible after two business
                         days. Your bank may or may not charge a fee for this
                         service. Redemptions of less than $1,000 will be sent by
                         check or electronic funds transfer.
                         This feature may be elected by completing the "Telephone

                   WHO MAY GUARANTEE YOUR SIGNATURE.
- -------------------------------------------------------------------------------
    A signature guarantee is a widely accepted way to protect you and the Fund by
    verifying the signature on your request. It may not be provided by a notary
    public. If the net asset value of the shares redeemed is $100,000 or less, John
    Hancock Funds may guarantee the signature. The following institutions may
    provide you with a signature guarantee, provided that the institution meets
    credit standards established by Investor Services: (i) a bank; (ii) a securities
    broker or dealer, including a government or municipal securities broker or
    dealer, that is a member of a clearing corporation or meets certain net capital
    requirements; (iii) a credit union having authority to issue signature
    guarantees; (iv) a savings and loan association, a building and loan
    association, a cooperative bank, a federal savings bank or association; or (v) a
    national securities exchange, a registered securities exchange or a clearing
    agency.

    If you have certificates for your shares, you must submit them with your stock
    power or a letter of instructions. Unless you specify to the contrary, any
    outstanding Class A shares will be redeemed before Class B shares. You may not
    redeem certificated shares by telephone.
    Due to the proportionately high cost of maintaining small accounts, the Fund
    reserves the right to redeem at net asset value all shares in an account which
    holds less than $100 (except accounts under retirement plans) and to mail the
    proceeds to the shareholder, or the transfer agent may impose an annual fee of
    $10.00. No account will be involuntarily redeemed or additional fee imposed, if
    the value of the account is in excess of the Fund's minimum initial investment
    or if the value of the account falls below the required minimum as a result of
    market action. No CDSC will be imposed on involuntary redemptions of shares.
    Shareholders will be notified before these redemptions are to be made or this
    fee is imposed, and will have 30 days to purchase additional shares to bring
    their account balance up to the required minimum. Unless the number of shares
    acquired by further purchases and dividend reinvestments, if any, exceeds the
    number of shares redeemed, repeated redemptions from a smaller account may
    eventually trigger this policy.

ADDITIONAL SERVICES AND PROGRAMS
 
EXCHANGE PRIVILEGE
 
If your investment objective changes, or if you wish to achieve further
diversification, John Hancock offers other funds with a wide range of investment
goals. Contact your registered representative or Selling Broker and request a
prospectus for the John Hancock funds that interest you. Read the prospectus
carefully before exchanging your shares. You can exchange shares of each class
of the Fund only for shares of the same class of another John Hancock fund. For
this purpose, John Hancock funds with only one class of shares will be treated
as Class A, whether or not they have been so designated.
 
- -------------------------------------------------------------------------------
                   YOU MAY EXCHANGE SHARES OF THE FUND ONLY
                   FOR SHARES OF THE SAME CLASS OF ANOTHER
                   JOHN HANCOCK FUND.
- -------------------------------------------------------------------------------
 
Exchanges between funds with shares that are not subject to a CDSC are based on
their respective net asset values. No sales charge or transaction charge is
imposed. Class B shares of the Fund that are subject to a CDSC may be exchanged
into Class B shares of another John Hancock fund without incurring the CDSC;
however, these shares will be subject to the CDSC schedule of the shares
acquired (except that exchanges into John Hancock Short-Term Strategic Income
Fund, John Hancock Limited-Term Government Fund and John Hancock Adjustable U.S.
Government Trust will be subject to the initial fund's CDSC). For purposes of
computing the CDSC payable upon redemption of shares acquired in an exchange,
the holding period of the original shares is added to the holding period of the
shares acquired in an exchange. However, if you exchange Class B shares
purchased prior to January 1, 1994 for Class B shares of any other John Hancock
Fund, you will be subject to the CDSC schedule in effect on your initial
purchase date.
 
You may exchange Class B shares of the Fund into shares of a John Hancock money
market fund at net asset value; however, you will continue to be subject to the
same CDSC upon redemption.
 
The Fund reserves the right to require you to keep previously exchanged shares
(and reinvested dividends) in the Fund for 90 days before you are permitted to
execute a new exchange. The Fund may also terminate or alter the terms of the
exchange privilege, upon 60 days' notice to shareholders.
 
An exchange of shares is treated as a redemption of shares of one fund and the
purchase of shares in another for Federal income tax purposes. An exchange may
result in a taxable gain or loss.
 
When you make an exchange, your account registration in both the existing and
new account must be identical. The exchange privilege is available only in
states where the exchange can be made legally.
 
Under exchange agreements with John Hancock Funds, certain dealers, brokers and
investment advisers may exchange their clients' Fund shares, subject to the
terms of those agreements and John Hancock Funds' right to reject or suspend
those exchanges at any time. Because of the restrictions and procedures under
those agreements, the exchanges may be subject to timing limitations and other
 
                                       23
<PAGE>   72
 
restrictions that do not apply to exchanges requested by shareholders directly,
as described above.
 
Because Fund performance and shareholders can be hurt by excessive trading, the
Fund reserves the right to terminate the exchange privilege for any person or
group that, in John Hancock Funds' judgment, is involved in a pattern of
exchanges that coincide with a "market timing" strategy that may disrupt the
Fund's ability to invest effectively according to its investment objective and
policies, or might otherwise affect the Fund and its shareholders adversely. The
Fund may also temporarily or permanently terminate the exchange privilege for
any person who makes seven or more exchanges out of the Fund per calendar year.
Accounts under common control or ownership will be aggregated for this purpose.
Although the Fund will attempt to give you prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time.
 
BY TELEPHONE
 
1. When you complete the application for your initial purchase of Fund shares,
   you automatically authorize exchanges by telephone unless you check the box
   indicating that you do not wish to authorize telephone exchanges.
 
2. Call 1-800-225-5291. Have the account number of your current fund and the
   exact name in which it is registered available to give to the telephone
   representative.
 
3. Investor Services employs the following procedures to confirm that
   instructions received by telephone are genuine. Your name, the account
   number, taxpayer identification number applicable to the account and other
   relevant information may be requested. In addition, telephone instructions
   are recorded.
 
IN WRITING
 
1. In a letter, request an exchange and list the following:
 
   -- the name and class of the Fund whose shares you currently own
   -- your account number
   -- the name(s) in which the account is registered
   -- the name of the fund in which you wish your exchange to be invested
   -- the number of shares, all shares or dollar amount you wish to exchange
 
   Sign your request exactly as the account is registered.
 
2. Mail the request and information to:
 
   John Hancock Investor Services Corporation
   P.O. Box 9116
   Boston, Massachusetts 02205-9116
 
                                       24

REINVESTMENT PRIVILEGE
 
1. You will not be subject to a sales charge on Class A shares reinvested in
   shares of any John Hancock fund that is otherwise subject to a sales charge
   as long as you reinvest within 120 days from the redemption date. If you paid
   a CDSC upon a redemption, you may reinvest at net asset value in the same
   class of shares from which you redeemed within 120 days. Your account will be
   credited with the amount of the CDSC previously charged, and the reinvested
   shares will continue to be subject to a CDSC. For purposes of computing the
   CDSC payable upon a subsequent redemption, the holding period of the shares
   acquired through reinvestment will include the holding period of the redeemed
   shares.
 
- -------------------------------------------------------------------------------
                   IF YOU REDEEM SHARES OF THE FUND, YOU MAY
                   BE ABLE TO REINVEST ALL OR PART OF THE
                   PROCEEDS IN SHARES OF THIS FUND OR ANOTHER
                   JOHN HANCOCK FUND WITHOUT PAYING AN
                   ADDITIONAL SALES CHARGE.
- -------------------------------------------------------------------------------
 
2. Any portion of your redemption may be reinvested in Fund shares or in shares
   of any of the other John Hancock funds, subject to the minimum investment
   limit of that fund.
 
3. To reinvest, you must notify Investor Services in writing. Include the Fund's
   name, the account number and class from which your shares were originally
   redeemed.
 
SYSTEMATIC WITHDRAWAL PLAN
1. You can elect the Systematic Withdrawal Plan at any time by completing the
   Account Privileges Application which is attached to this Prospectus. You can
   also obtain this application by calling your registered representative or by
   calling 1-800-225-5291.
 
2. To be eligible, you must have at least $5,000 in your account.
 
- -------------------------------------------------------------------------------
                   YOU CAN PAY ROUTINE BILLS FROM YOUR
                   ACCOUNT, OR MAKE PERIODIC DISBURSEMENTS OF
                   FUNDS FROM YOUR RETIREMENT ACCOUNT TO
                   COMPLY WITH IRS REGULATIONS.
- -------------------------------------------------------------------------------
 
3. Payments from your account can be made monthly, quarterly, semi-annually or
   annually or on a selected monthly basis to yourself or any other designated
   payee.
 
4. There is no limit on the number of payees you may authorize, but all payments
   must be made at the same time or intervals.
 
5. It is not advantageous to maintain a Systematic Withdrawal Plan concurrently
   with purchases of additional Class A or Class B shares, because you may be
   subject to initial sales charges on your purchases of Class A shares or to a
   CDSC on your redemptions of Class B shares. In addition, your redemptions are
   taxable events.
 
6. Redemptions will be discontinued if the U.S. Postal Service cannot deliver
   your checks or if deposits to a bank account are returned for any reason.
 
MONTHLY AUTOMATIC ACCUMULATION PROGRAM (MAAP)
1. You can authorize an investment to be automatically withdrawn each month from
   your bank, for investment in Fund shares under the "Automatic Investing" and
   "Bank Information" sections of the Account Privileges Application.
 
- -------------------------------------------------------------------------------
                   YOU CAN MAKE AUTOMATIC INVESTMENTS AND
                   SIMPLIFY YOUR INVESTING.
- -------------------------------------------------------------------------------
 
                                       25

2. You can also authorize automatic investment through payroll deduction by
   completing the "Direct Deposit Investing" section of the Account Privileges
   Application.
 
3. You can terminate your Monthly Automatic Accumulation Program plan at any
   time.
 
4. There is no charge to you for this program, and there is no cost to the Fund.
 
5. If you have payments being withdrawn from a bank account and we are notified
   that the account has been closed, your withdrawals will be discontinued.
 
GROUP INVESTMENT PROGRAM
 
1. An individual account will be established for each participant, but the
   initial sales charge for Class A shares will be based on the aggregate dollar
   amount of all participants' investments. To determine how to qualify for this
   program, contact your registered representative or call 1-800-225-5291.
 
- -------------------------------------------------------------------------------
                   ORGANIZED GROUPS OF AT LEAST FOUR PERSONS
                   MAY ESTABLISH ACCOUNTS.
- -------------------------------------------------------------------------------
 
2. The initial aggregate investment of all participants in the group must be at
   least $250.
 
3. There is no additional charge for this program. There is no obligation to
   make investments beyond the minimum, and you may terminate the program at any
   time.
 
INVESTMENTS, TECHNIQUES AND RISK FACTORS
RESTRICTED AND ILLIQUID SECURITIES.  The Fund may invest up to 10% of its net
assets in illiquid investments, which include repurchase agreements maturing in
more than seven days, restricted securities and securities not readily
marketable. The Fund may also invest up to 10% of its assets in restricted
securities eligible for resale to certain institutional investors pursuant to
Rule 144A under the Securities Act of 1933. To the extent that the Fund's
holdings of participation interests, COPs and inverse floaters are determined to
be illiquid, such holdings will be subject to the 10% restriction on illiquid
investments.
 
LENDING OF SECURITIES AND REPURCHASE AGREEMENTS.  For the purpose of realizing
additional (taxable) income, the Fund may lend to broker-dealers portfolio
securities amounting to not more than 33% of its total assets taken at current
value or may enter into repurchase agreements. In a repurchase agreement, the
Fund buys a security subject to the right and obligation to sell it back to the
issuer at the same price plus accrued interest. These transactions must be fully
collateralized at all times. The Fund may reinvest any cash collateral in
short-term highly liquid debt securities. However, they may involve some credit
risk to the Fund if the other party should default on its obligation and the
Fund is delayed in or prevented from recovering the collateral. Securities
loaned by the Fund will remain subject to fluctuations of market value.
 
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES.  The Fund may purchase securities
on a forward or "when-issued" basis and may purchase or sell securities
 
                                       26
<PAGE>   75
 
on a forward commitment basis to hedge against anticipated changes in interest
rates and prices. When the Fund engages in such transactions, it relies on the
seller or the buyer, as the case may be, to consummate the transaction. Failure
to consummate the transaction may result in the Fund's losing the opportunity to
obtain an advantageous price and yield. If the Fund chooses to dispose of the
right to acquire a when-issued security prior to its acquisition or dispose of
its right to deliver or receive against a forward commitment, it can incur a
taxable gain or a loss.
 
SHORT TERM TRADING AND PORTFOLIO TURNOVER.  Short-term trading means the
purchase and subsequent sale of a security after it has been held for a
relatively brief period of time. Short term trading may have the effect of
increasing portfolio turnover and may increase net short-term capital gains,
distributions from which would be taxable to shareholders as ordinary income.
The Fund does not intend to invest for the purpose of seeking short-term
profits. The Fund's portfolio securities may be changed, however, without regard
to the holding period of these securities (subject to certain tax restrictions),
when the Adviser deems that this action will help achieve the Fund's objective
given a change in an issuer's operations or changes in general market
conditions. The Fund's portfolio turnover rate is set forth in the table under
the caption "Financial Highlights."
 
OPTIONS AND FUTURES TRANSACTIONS.  The Fund may buy and sell options contracts
on securities and debt security indices, interest rate and municipal bond index
futures contracts and options on such futures contracts. Options and futures
contracts are bought and sold to manage the Fund's exposure to changing interest
rates and security prices. Some options and futures strategies, including
selling futures, buying puts and writing calls, tend to hedge a Fund's
investment against price fluctuations. Other strategies, including buying
futures, writing puts, and buying calls, tend to increase market exposure.
Options and futures may be combined with each other or with forward contracts in
order to adjust the risk and return characteristics of the overall strategy. The
Fund may invest in options and futures based on debt securities and municipal
bond indices (securities indices).
 
Options and futures can be volatile investments and involve certain risks. If
the Adviser applies a hedge at an inappropriate time or judges market conditions
incorrectly, options and futures strategies may lower the Fund's return. The
Fund could also experience losses if the prices of its options and futures
positions were poorly correlated with its other investments, or if it could not
close out its positions because of an illiquid secondary market. Options and
futures do not pay interest, but may produce taxable capital gains or losses.
 
The Fund will not engage in a transaction in futures or options on futures if,
immediately thereafter, the sum of initial margin deposits and premiums required
to establish positions in futures contracts and options on futures would exceed
5% of the Fund's net assets. The loss incurred by the Fund investing in futures
contracts and in writing options on futures is potentially unlimited and may
exceed the amount of any premium received. The Fund's transactions in options
and futures contracts may be limited by the requirements of the Code for
qualification as a regulated investment company. See the Statement of Additional
Information
 
                                       27
<PAGE>   76
 
for further discussion of options and futures transactions, including tax
effects and investment risks.
 
MUNICIPAL LEASE OBLIGATIONS.  The Fund may purchase participation interests
which give the Fund an undivided pro rata interest in the tax exempt security.
For certain participation interests, the Fund will have the right to demand
payment, on a specified number of days' notice for all or any part of the Fund's
participation interest in the tax exempt security plus accrued interest.
Participation interests, which are determined to be not readily marketable, will
be considered illiquid for purposes of the Fund's 10% restriction on investment
in securities.
 
The Fund may also invest in Certificates of Participation ("COP's") which
provide participation interests in lease revenues. Each COP represents a
proportionate interest in or right to the lease-purchase payment made under
municipal lease obligations or installment sales contracts. Municipal lease
obligations are issued by a state or municipal financing authority to provide
funds for the construction of facilities (e.g., schools, dormitories, office
buildings or prisons) or the acquisition of equipment. Certain municipal lease
obligations may trade infrequently. Accordingly, COPs will be purchased and
monitored pursuant to analysis by the Adviser and reviewed according to
procedures by the Board of Trustees which consider various factors in
determining the liquidity risk. COPs will not be considered illiquid for
purposes of the Fund's 10% limitation on illiquid securities provided the
Adviser determines that there is a readily available market for such securities.
An investment in COPs is subject to the risk that a municipality may not
appropriate sufficient funds to meet payments on the underlying lease
obligation. See the Statement of Additional Information for additional
discussion of participation interests and municipal lease obligations.
 
DERIVATIVE INSTRUMENTS.  The Fund may purchase or enter into derivative
instruments to enhance return, to hedge against fluctuations in interest rates
or securities prices, to change the duration of the Fund's fixed income
portfolio or as a substitute for the purchase or sale of securities. The Fund's
investments in derivative securities may include certain floating rate and
indexed securities. The Fund's transactions in derivative contracts may include
the purchase or sale of futures contracts on securities or indices; options on
futures contracts; and options on securities or indices. All of the Funds'
transactions in derivative instruments involve a risk of loss or depreciation
due to unanticipated adverse changes in interest rates or securities prices. The
loss on derivative contracts may exceed the Fund's initial investment in these
contracts. In addition, the Fund may lose the entire premium paid for purchased
options that expire before they can be profitably exercised by the Fund. The
Fund may realize taxable income or gain from its transactions in derivative
contracts, distributions of which will be taxable to shareholders.
 
INDEXED SECURITIES.  The Fund may invest in indexed securities, including
floating rate securities that are subject to a maximum interest rate ("capped
floaters") and leveraged inverse floating rate securities ("inverse floaters")
(up to 10% of the Fund's total assets). The interest rate or, in some cases, the
principal payable at the maturity of an indexed security may change positively
or inversely in relation to
 
                                       28
<PAGE>   77
 
one or more interest rates, financial indices or other financial indicators
("reference prices"). An indexed security may be leveraged to the extent that
the magnitude of any change in the interest rate or principal payable on an
indexed security is a multiple of the change in the reference price. Thus,
indexed securities may decline in value due to adverse market changes in
interest rates or other reference prices.
 
RISKS ASSOCIATED WITH DERIVATIVE SECURITIES AND CONTRACTS.  The risks associated
with the Fund's transactions in derivative securities and contracts may include
some or all of the following:
Market Risk.  Investments in floating rate and indexed securities are subject to
the interest rate and other market risks described above. Entering into a
derivative contract involves a risk that the applicable market will move against
the Fund's position and that the Fund will incur a loss. For derivative
contracts other than purchased options, this loss may exceed the amount of the
initial investment made or the premium received by the Fund.
Leverage and Volatility Risk.  Derivative instruments may sometimes increase or
leverage the Fund's exposure to a particular market risk. Leverage enhances the
price volatility of derivative instruments held by the Fund. The Fund may
partially offset the leverage inherent in derivative contracts by maintaining a
segregated account consisting of cash and liquid, high grade debt securities, by
holding offsetting portfolio securities or contracts or by covering written
options.
Correlation Risk.  A Fund's success in using derivative instruments to hedge
portfolio assets depends on the degree of price correlation between the
derivative instrument and the hedged asset. Imperfect correlation may be caused
by several factors, including temporary price disparities among the trading
markets for the derivative instrument, the assets underlying the derivative
instrument and the Fund's portfolio assets.
Credit Risk.  Derivative securities and over-the-counter derivative contracts
involve a risk that the issuer or counterparty will fail to perform its
contractual obligations.
Liquidity and Valuation Risk.  Some derivative securities are not readily
marketable or may become illiquid under adverse market conditions. In addition,
during periods of extreme market volatility, a commodity or exchange may suspend
or limit trading in an exchange-traded derivative contract, which may make the
contract temporarily illiquid and difficult to price. The staff of the SEC takes
the position that certain over-the-counter options are subject to the Fund's 10%
limit on illiquid investments. The Fund's ability to terminate over-the-counter
derivative contracts may depend on the cooperation of the counterparties to such
contracts. For thinly traded derivative securities and contracts, the only
source of price quotations may be the selling dealer or counterparty.

* Net amount subject to Federal income tax after deductions and exemptions. It
  is assumed that an investor filing a single return is not a "head of
  household," a "married individual filing a separate return," or a "surviving
  spouse." The table does not take into account the effects of reductions in the
  deductibility of itemized deductions or the phaseout of personal exemptions
  for taxpayers with adjusted gross incomes in excess of specified amounts.
  Further, the table does not attempt to show any alternative minimum tax
  consequences, which will depend on each shareholder's particular tax situation
  and may vary according to what portion, if any, of the Fund's exempt-interest
  dividends is attributable to interest on certain private activity bonds for
  any particular taxable year. No assurance can be given that the Fund will
  achieve any specific tax-exempt yield or that all of its income distributions
  will be tax-exempt. Distributions attributable to any taxable income or
  capital gains realized by the Fund will not be tax-exempt.
 
The information set forth above is as of the date of this Prospectus. Subsequent
tax law changes could result in prospective or retroactive changes in the tax
brackets, tax rates, and tax-equivalent yields set forth above.

                                  EXHIBIT B

                     AGREEMENT AND PLAN OF REORGANIZATION


     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made this
18th day of March, 1996, by and between John Hancock Tax-Free Bond Fund (the
"Acquiring Fund"), a Massachusetts business trust, and John Hancock Tax-Exempt
Income Fund (the "Acquired Fund"), a Massachusetts business trust, each with
their principal place of business at 101 Huntington Avenue, Boston,
Massachusetts 02199. The Acquiring Fund and the Acquired Fund are sometimes
referred to collectively herein as the "Funds" and individually as a "Fund."

     This Agreement is intended to be and is adopted as a plan of
"reorganization," as such term is used in Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"). The reorganization will consist of the
transfer of all of the assets of the Acquired Fund to the Acquiring Fund in
exchange solely for the issuance of Class A and Class B shares of beneficial
interest of the Acquiring Fund (the "Acquiring Fund Shares") to the Acquired
Fund and the assumption by the Acquiring Fund of all of the liabilities of the
Acquired Fund, followed by the distribution by the Acquired Fund, on or promptly
after the Closing Date hereinafter referred to, of the Acquiring Fund Shares to
the shareholders of the Acquired Fund in liquidation and termination of the
Acquired Fund as provided herein, all upon the terms and conditions set forth in
this Agreement.

     In consideration of the premises of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:


1.  TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ASSUMPTION OF
    LIABILITIES AND ISSUANCE OF ACQUIRING FUND SHARES; LIQUIDATION OF THE
    ACQUIRED FUND

     1.1 The Acquired Fund will transfer all of its assets (consisting, without
limitation, of portfolio securities and instruments, dividends and interest
receivables, cash and other assets), as set forth in the statement of assets and
liabilities referred to in Paragraph 7.2 hereof (the "Statement of Assets and
Liabilities"), to the Acquiring Fund free and clear of all liens and
encumbrances, except as otherwise provided herein, in exchange for (i) the
assumption by the Acquiring Fund of the known and unknown liabilities of the
Acquired Fund, including the liabilities set forth in the Statement of Assets
and Liabilities (the "Acquired Fund Liabilities"), which shall be assigned and
<PAGE>   81
transferred to the Acquiring Fund by the Acquired Fund and assumed by the
Acquiring Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund,
for distribution pro rata by the Acquired Fund to its Class A and Class B
shareholders in proportion to their respective ownership of Class A and Class B
shares of beneficial interest of the Acquired Fund, as of the close of business
on the closing date (the "Closing Date"), of a number of the Acquiring Fund
Shares having an aggregate net asset value equal to the value of the assets,
less such liabilities (herein referred to as the "net value of the assets"),
attributable to the corresponding class of the Acquired Fund so transferred,
assumed, assigned and delivered, all determined as provided in Paragraph 2.1 
hereof and as of a date and time as specified therein. Such transactions shall
take place at the closing provided for in Paragraph 3.1 hereof (the "Closing").
All computations shall be provided by Investors Bank and Trust Company (the 
"Custodian"), as custodian and pricing agent for the Acquiring Fund and the 
Acquired Fund.

     1.2  The Acquired Fund has provided the Acquiring Fund with a list of the
current securities holdings of the Acquired Fund as of the date of execution of
this Agreement. The Acquired Fund reserves the right to sell any of these
securities (except to the extent sales may be limited by representations made in
connection with issuance of the tax opinion provided for in paragraph 8.6
hereof) but will not, without the prior approval of the Acquiring Fund, acquire
any additional securities other than securities of the type in which the
Acquiring Fund is permitted to invest.

     1.3  The Acquiring Fund and the Acquired Fund shall each bear its own
expenses in connection with the transactions contemplated by this Agreement.

     1.4  On or as soon after the Closing Date as is conveniently practicable
(the "Liquidation Date"), the Acquired Fund will liquidate and distribute pro
rata to shareholders of record of the applicable class (the "Acquired Fund
shareholders"), determined as of the close of regular trading on the New York
Stock Exchange on the Closing Date, the Acquiring Fund Shares received by the
Acquired Fund pursuant to Paragraph 1.1 hereof. Such liquidation and
distribution will be accomplished by the transfer of the Acquiring Fund Shares
then credited to the account of the Acquired Fund on the books of the Acquiring
Fund, to open accounts on the share records of the Acquiring Fund in the names
of the Acquired Fund shareholders and representing the respective pro rata
number and class of Acquiring Fund Shares due such shareholders. Acquired Fund
shareholders who own Class A shares of the Acquired Fund will receive Class A
Acquiring Fund Shares, and Acquired Fund shareholders who own Class B shares of
the Acquired Fund will receive Class B Acquiring Fund Shares. If shares of the
Acquired Fund acquired in an exchange from another mutual fund are subject

                                      B-2
<PAGE>   82

to a contingent deferred sales charge ("CDSC") immediately prior to the
Closing, the successor Acquiring Fund Shares received in the Reorganization
shall be subject to the same CDSC, including all terms and conditions for
computing and applying such CDSC. The Acquiring Fund shall not issue
certificates representing Acquiring Fund Shares in connection with such
exchange.

     1.5  The Acquired Fund shareholders holding certificates representing their
ownership of shares of beneficial interest of the Acquired Fund shall surrender
such certificates or deliver an affidavit with respect to lost certificates in
such form and accompanied by such surety bonds as the Acquired Fund may require
(collectively, an "Affidavit"), to John Hancock Investor Services Corporation
prior to the Closing Date. Any Acquired Fund share certificate which remains
outstanding on the Closing Date shall be deemed to be cancelled, shall no longer
evidence ownership of shares of beneficial interest of the Acquired Fund and
shall evidence ownership of Acquiring Fund Shares. Unless and until any such
certificate shall be so surrendered or an Affidavit relating thereto shall be
delivered, dividends and other distributions payable by the Acquiring Fund
subsequent to the Liquidation Date with respect to Acquiring Fund Shares shall
be paid to the holder of such certificate(s), but such shareholders may not
redeem or transfer Acquiring Fund Shares received in the Reorganization. The
Acquiring Fund will not issue stock certificates in the Reorganization.

     1.6  Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than the registered holder of the Acquired Fund Shares on the books
of the Acquired Fund as of that time shall, as a condition of such issuance and
transfer, be paid by the person to whom such Acquiring Fund Shares are to be
issued and transferred.

     1.7  The existence of the Acquired Fund shall be terminated as promptly as
practicable following the Liquidation Date.

     1.8  Any reporting responsibility of the Acquired Fund, including, but not
limited to, the responsibility for filing of regulatory reports, tax returns, or
other documents with the Securities and Exchange Commission (the "Commission"),
any state securities commissions, and any federal, state or local tax
authorities or any other relevant regulatory authority, is and shall remain the
responsibility of the Acquired Fund.


2.  VALUATION

     2.1  The net asset values of the Class A and Class B Acquiring Fund Shares
and the net values of the assets and


                                      B-3
<PAGE>   83

liabilities of the Acquired Fund attributable to its Class A and Class B shares
to be transferred or assumed shall, in each case, be determined as of the close
of business (4:00 p.m. Boston time) on the Closing Date. The net asset values of
the Class A and Class B Acquiring Fund Shares shall be computed by the Custodian
in the manner set forth in the Acquiring Fund's Declaration of Trust, as
amended, or By-laws and the Acquiring Fund's then-current prospectus and
statement of additional information and shall be computed in each case to not
fewer than four decimal places. The net values of the assets of the Acquired
Fund attributable to its Class A and Class B shares to be transferred shall be
computed by the Custodian by calculating the value of the assets of each class
transferred by the Acquired Fund and by subtracting therefrom the amount of the
liabilities of each respective class assigned and transferred to and assumed by
the Acquiring Fund on the Closing Date, said assets and liabilities to be valued
in the manner set forth in the Acquired Fund's then-current prospectus and
statement of additional information and shall be computed in each case to not
fewer than four decimal places.

     2.2  The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Fund's
assets shall be determined by dividing the value of the Acquired Fund's assets
attributable to a class, less the liabilities attributable to that class assumed
by the Acquiring Fund, by the Acquiring Fund's net asset value per share of the
same class, all as determined in accordance with Paragraph 2.1 hereof.

     2.3  All computations of value shall be made by the Custodian in accordance
with its regular practice as pricing agent for the Funds.


3.   CLOSING AND CLOSING DATE

     3.1  The Closing Date shall be May 3, 1996 or such other date on or 
before December 31, 1996 as the parties may agree. The Closing shall be held as
of 5:00 p.m. at the offices of the Funds, 101 Huntington Avenue, Boston,
Massachusetts 02199, or at such other time and/or place as the parties may
agree.

     3.2  Portfolio securities that are not held in book-entry form in the
name of the Custodian as record holder for the Acquired Fund shall be presented
by the Acquired Fund to the Custodian for examination no later than five
business days preceding the Closing Date. Portfolio securities which are not
held in book-entry form shall be delivered by the Acquired Fund to the
Custodian for the account of the Acquiring Fund on the Closing 


                                      B-4
<PAGE>   84

Date, duly endorsed in proper form for transfer, in such condition as
to constitute good delivery thereof in accordance with the custom of brokers,
and shall be accompanied by all necessary federal and state stock transfer
stamps or a check for the appropriate purchase price thereof. Portfolio
securities held of record by the Custodian in book-entry form on behalf of the
Acquired Fund shall be delivered to the Acquiring Fund by the Custodian by
recording the transfer of beneficial ownership thereof on its records. The cash
delivered shall be in the form of currency or by the Custodian crediting the
Acquiring Fund's account maintained with the Custodian with immediately
available funds.

     3.3  In the event that on the Closing Date (a) the New York Stock Exchange
shall be closed to trading or trading thereon shall be restricted or (b) trading
or the reporting of trading on said Exchange or elsewhere shall be disrupted so
that accurate appraisal of the value of the net assets of the Acquiring Fund or
the Acquired Fund is impracticable, the Closing Date shall be postponed until
the first business day after the day when trading shall have been fully resumed
and reporting shall have been restored; provided that if trading shall not be
fully resumed and reporting restored on or before December 31, 1996, this
Agreement may be terminated by the Acquiring Fund or by the Acquired Fund upon
the giving of written notice to the other party.

     3.4  The Acquired Fund shall deliver at the Closing a list of the names,
addresses, federal taxpayer identification numbers and backup withholding and
nonresident alien withholding status of the Acquired Fund shareholders and the
number of outstanding shares of each class of beneficial interest of the
Acquired Fund owned by each such shareholder, all as of the close of business on
the Closing Date, certified by its Treasurer, Secretary or other authorized
officer (the "Shareholder List"). The Acquiring Fund shall issue and deliver to
the Acquired Fund a confirmation evidencing the Acquiring Fund Shares to be
credited on the Closing Date, or provide evidence satisfactory to the Acquired
Fund that such Acquiring Fund have been credited to the Acquired Fund's account
on the books of the Acquiring Fund. At the Closing, each party shall deliver to
the other such bills of sale, checks, assignments, stock certificates, receipts
or other documents as such other party or its counsel may reasonably request.


4.  REPRESENTATIONS AND WARRANTIES

     4.1  The Acquired Fund represents, warrants and covenants to the Acquiring
Fund as follows:


                                      B-5
<PAGE>   85

             (a)  The Acquired Fund is a voluntary association with transferable
         shares of the type commonly referred to as a business trust, duly
         organized and validly existing under the laws of The Commonwealth of
         Massachusetts and has the power to own all of its properties and assets
         and, subject to approval by the shareholders of the Acquired Fund, to
         carry out the transactions contemplated by this Agreement. The Acquired
         Fund is not required to qualify to do business in any jurisdiction in
         which it is not so qualified or where failure to qualify would subject
         it to any material liability or disability. The Acquired Fund has all
         necessary federal, state and local authorizations to own all of its
         properties and assets and to carry on its business as now being
         conducted;

             (b)  The Acquired Fund is a registered investment company
         classified as a management company and its registration with the
         Commission as an investment company under the Investment Company Act
         of 1940, as amended (the "1940 Act"), is in full force and effect. The
         Acquired Fund is a diversified fund;

             (c)  The Acquired Fund is not, and the execution, delivery and
         performance of its obligations under this Agreement will not result, in
         violation of any provision of the Acquired Fund's Declaration of Trust,
         as amended, or By-Laws or of any agreement, indenture, instrument,
         contract, lease or other undertaking to which the Acquired Fund is a
         party or by which it is bound;

             (d)  Except as otherwise disclosed in writing and accepted by the
         Acquiring Fund, no material litigation or administrative proceeding or
         investigation of or before any court or governmental body is currently
         pending or threatened against the Acquired Fund or any of the Acquired
         Fund's properties or assets. The Acquired Fund knows of no facts which
         might form the basis for the institution of such proceedings, and the
         Acquired Fund is not a party to or subject to the provisions of any
         order, decree or judgment of any court or governmental body which
         materially and adversely affects the Acquired Fund's business or its
         ability to consummate the transactions herein contemplated;

             (e)  The Acquired Fund has no material contracts or other
         commitments (other than this Agreement or agreements for the purchase
         of securities entered into in the ordinary course of business and
         consistent with its obligations under this Agreement) which will not
         be terminated without liability to the Acquired Fund at or prior to
         the Closing Date;

                                      B-6
<PAGE>   86

             (f)  The audited statement of assets and liabilities, including the
         schedule of investments, of the Acquired Fund as of December 31, 1995
         and the related statement of operations and the statement of changes in
         net assets for the years ended December 31, 1995 and 1994 (copies of
         which have been furnished to the Acquiring Fund) present fairly in all
         material respects the financial condition of the Acquired Fund as of
         December 31, 1995 and the results of its operations for the period then
         ended in accordance with generally accepted accounting principles
         consistently applied, and there were no known actual or contingent
         liabilities of the Acquired Fund as of the respective dates thereof not
         disclosed therein;

             (g)  Since December 31, 1995, there has not been any material 
         adverse change in the Acquired Fund's financial condition, assets, 
         liabilities, or business other than changes occurring in the ordinary
         course of business, or any incurrence by the Acquired Fund of 
         indebtedness maturing more than one year from the date such 
         indebtedness was incurred, except as otherwise disclosed to and 
         accepted by the Acquiring Fund;
             
             (h)  At the date hereof and by the Closing Date, all federal,
         state and other tax returns and reports, including information returns
         and payee statements, of the Acquired Fund required by law to have
         been filed or furnished by such dates shall have been filed or
         furnished, and all federal, state and other taxes, interest and
         penalties shall have been paid so far as due, or provision shall have
         been made for the payment thereof, and to the best of the Acquired
         Fund's knowledge no such return is currently under audit and no
         assessment has been asserted with respect to such returns or reports;

             (i)  The Acquired Fund has elected to be treated as a regulated
         investment company for federal income tax purposes, has qualified as
         such for each taxable year of its operation and will qualify as such as
         of the Closing Date with respect to its final taxable year ending on
         the Closing Date;

             (j)  The authorized capital of the Acquired Fund consists of an
         unlimited number of shares of beneficial interest, no par value. All
         issued and outstanding shares of beneficial interest of the Acquired
         Fund are, and at the Closing Date will be, duly and validly issued and
         outstanding, fully paid and nonassessable by the Acquired Fund. All of
         the issued and outstanding shares of beneficial interest of the
         Acquired Fund will, at the time of Closing, be held by the persons and
         in the amounts and classes set

                                      B-7
<PAGE>   87

         forth in the Shareholder List submitted to the Acquiring Fund pursuant
         to Paragraph 3.4 hereof. The Acquired Fund does not have outstanding
         any options, warrants or other rights to subscribe for or purchase any

         interest, nor is there outstanding any security convertible into any of
         its shares of beneficial interest;

            (k)  The execution, delivery and performance of this Agreement
         has been duly authorized by all necessary action on the part of the

             (d)  The basis of the assets of the Acquired Fund acquired by
         the Acquiring Fund will be, in each instance, the same as the basis of
         those assets in the hands of the Acquired Fund immediately prior to the
         transfer;

             (e)  The tax holding period of the assets of the Acquired Fund

             (h)  The tax holding period of the Acquiring Fund Shares 
         received by the Acquired Fund shareholders will include, for each

         the date of the exchange.

                            ORGANIZATION OF THE FUND

     The Fund is a diversified open-end management investment company organized
as a business trust under the laws of The Commonwealth of Massachusetts.  Prior
to the approval of John Hancock Advisers, Inc. (the "Investment Adviser") as
the Fund's adviser, the Fund was known as Transamerica Tax-Exempt Bond Fund.

                       INVESTMENT OBJECTIVE AND POLICIES

     INVESTMENT OBJECTIVE.  As discussed under "Investment Objective and
Policies" in the Prospectus, the investment objective of the Fund is to obtain
as high a level of income exempt from federal income taxes as is consistent
with preservation of capital.  The Fund seeks to achieve its objective by
investing primarily in municipal bonds which are rated at the time of purchase
within the four highest ratings and municipal notes which are rated at the time
of purchase within the two highest ratings assigned by Moody's Investors
Service, Inc. ("Moody's"), Standard & Poor's Ratings Group ("S&P") or Fitch
Investors Service, Inc. ("Fitch"); municipal bonds and notes which, if unrated,
are determined to be of comparable quality by John Hancock Advisers, Inc. (the
"Investment Adviser"); and municipal commercial paper rated within the two
highest quality ratings (collectively, "Municipal Obligations").  Securities in
which the Fund may invest may not earn as high a level of current income as
lower quality securities which have greater market risk and more fluctuation in
market value.

     DESCRIPTION OF MUNICIPAL OBLIGATIONS.  In seeking to achieve its
investment objective, the Fund invests in a variety of Municipal Obligations
which consist of Municipal Bonds, Municipal Notes and Municipal Commercial
Paper, the interest on which in the opinion of the bond issuer's counsel (not
the Fund's counsel) is exempt from federal income tax.

     Municipal Bonds.  Municipal bonds are issued to obtain funds for various
public purposes including the construction of a wide range of public facilities
such as airports, highways, bridges, schools, hospitals, housing, mass
transportation, streets and water and sewer works.  Other public purposes for
which Municipal Bonds may be issued include refunding outstanding obligations,
obtaining funds for general operating expenses and obtaining funds to lend to
other public institutions and facilities.  In addition, certain types of
industrial development bonds are issued by or on behalf of public authorities
to obtain funds for many types of local, privately operated facilities.  Such
debt instruments are considered municipal obligations if the interest paid on
them is exempt from federal income tax.  The payment of principal and interest
by issuers of certain obligations purchased by the Fund may be guaranteed by a
letter of credit, note repurchase agreement, insurance or other credit facility
agreement offered by a bank or other financial institution.  Such guarantees
and the creditworthiness of guarantors will be considered by the Investment
Adviser in determining whether a Municipal Obligation meets the Fund's
investment quality requirements.  No assurance can be given that a municipality
or guarantor will be able to satisfy the payment of principal or interest on a
municipal obligation.

     Municipal Notes.  Municipal Notes are short-term obligations of
municipalities, generally with a maturity ranging from six months to three
years.  The principal types of such Notes include tax, bond and revenue
anticipation notes and project notes.

     Municipal Commercial Paper.  Municipal Commercial Paper is a short-term
obligation of a municipality, generally issued at a discount with a maturity of
less than one year.  Such paper is


                                      -2-
<PAGE>   110
likely to be issued to meet seasonal working capital needs of a municipality or
interim construction financing.  Municipal Commercial Paper is backed in many
cases by letters of credit, lending agreements, note repurchase agreements or
other credit facility agreements offered by banks and other institutions.

     Federal tax legislation enacted in the 1980's placed substantial new
restrictions on the issuance of the bonds described above and in some cases
eliminated the ability of state or local governments to issue Municipal
Obligations for some of the above purposes.  Such restrictions do not affect
the Federal income tax treatment of Municipal Obligations in which the Fund may
invest which were issued prior to the effective dates of the provisions
imposing such restrictions.  The effect of these restrictions may be to reduce
the volume of newly issued Municipal Obligations.

     Issuers of Municipal Obligations are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Act, and laws, if any, which may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations.  There is also the possibility that as a result of
litigation or other conditions the power or ability of any one or more issuers
to pay when due the principal of and interest on their Municipal Obligations
may be affected.

     The yields of Municipal Bonds depend upon, among other things, general
money market conditions, general conditions of the Municipal Bond market, size
of a particular offering, the maturity of the obligation and rating of the
issue.  The ratings of S&P, Moody's and Fitch represent their respective
opinions of the quality of the Municipal Bonds they undertake to rate.  It
should be emphasized, however, that ratings are general and not absolute
standards of quality.  Consequently, Municipal Bonds with the same maturity,
coupon and rating may have different yields and Municipal Bonds of the same
maturity and coupon with different ratings may have the same yield.  See
Appendix A for a description of ratings.  Many issuers of securities choose not
to have their obligations rated.  Although unrated securities eligible for
purchase by the Fund must be determined to be comparable in quality to
securities having certain specified ratings, the market for unrated securities
may not be as broad as for rated securities since many investors rely on rating
organizations for credit appraisal.

     VARIABLE OR FLOATING RATE OBLIGATIONS.  As discussed under "Investment
Objective and Policies" in the Prospectus, certain of the obligations in which
the Fund may invest may be variable or floating rate obligations on which the
interest rate is adjusted at predesignated periodic intervals (variable rate)
or when there is a change in the market rate of interest on which the interest
rate payable on the obligation is met is based (floating rate).  Variable or
floating rate obligations may include a demand feature which entitles the
purchaser to demand prepayment of the principal amount prior to stated
maturity.  Also, the issuer may have a corresponding right to prepay the
principal amount prior to maturity.  As with any other type of debt security,
the marketability of variable or floating rate instruments may vary depending
upon a number of factors, including the type of issuer and the terms of the
instruments.  The Fund may also invest in more recently developed floating rate
instruments which are created by dividing a municipal security's interest rate
into two or more different components.  Typically, one component ("floating
rate component" or "FRC") pays an interest rate that is reset periodically
through an auction process or by reference to an interest rate index.  A second
component ("inverse floating rate component" or "IFRC") pays an interest rate
that varies inversely with changes to market rates of interest, because the
interest paid to the IFRC holders is generally determined by subtracting a
variable or floating rate from a predetermined amount (i.e., the difference
between the total interest paid by the municipal security and that paid by the
FRC).  The Fund may


                                      -3-
<PAGE>   111
purchase FRC's without limitation.  Up to 10% of the Fund's total assets may be
invested in IFRC's in an attempt to protect against a reduction in the income
earned on the Fund's other investments due to a decline in interest rates.  The
extent of increases and decreases in the value of an IFRC generally will be
greater than comparable changes in the value of an equal principal amount of a
fixed-rate municipal security having similar credit quality, redemption
provisions and maturity.  To the extent that such instruments are not readily
marketable, as determined by the Investment Adviser pursuant to guidelines
adopted by the Board of Trustees, they will be considered illiquid for purposes
of the Fund's 10% investment restriction on investment in non-readily
marketable securities.

     PARTICIPATION INTERESTS.  The Fund may purchase from financial
institutions tax exempt participation interests in tax exempt securities.  A
participation interest gives the Fund an undivided interest in the tax exempt
security in the proportion that the Fund's participation interest bears to the
total amount of the tax exempt security.  For certain participation interests,
the Fund will have the right to demand payment, on a specified number of days'
notice, for all or any part of the Fund's participation interest in the tax
exempt security plus accrued interest.  Participation interests, which are
determined to be not readily marketable, will be considered as such for
purposes of the Fund's 10% investment restriction on investment in non-readily
marketable illiquid securities.  The Fund may also invest in Certificates of
Participation (COP's) which provide participation interests in lease revenues.
Each Certificate represents a proportionate interest in or right to the
lease-purchase payment made under municipal lease obligations or installment
sales contracts.  Typically, municipal lease obligations are issued by a state
or municipal financing authority to provide funds for the construction of
facilities (e.g., schools, dormitories, office buildings or prisons) or the
acquisition of equipment.  The facilities are typically used by the state or
municipality pursuant to a lease with a financing authority.  Certain municipal
lease obligations may trade infrequently.  Participation interests in municipal
lease obligations will not be considered illiquid for purposes of the Fund's
10% limitation on illiquid securities provided the Investment Adviser
determines that there is a readily available market for such securities.  In
reaching liquidity decisions, the Investment Adviser will consider, among
others, the following factors: (1) the frequency of trades and quotes for the
security; (2) the number of dealers wishing to purchase or sell the security
and the number of other potential purchasers; (3) dealer undertakings to make a
market in the security and (4) the nature of the security and the nature of the
marketplace trades (e.g., the time needed to dispose of the security, the
method of soliciting offers and the mechanics of the transfer.)  With respect
to municipal lease obligations, the Investment Adviser also considers: (1) the
willingness of the municipality to continue, annually or biannually, to
appropriate funds for payment of the lease; (2) the general credit quality of
the municipality and the essentiality to the municipality of the property
covered by the lease; (3) an analysis of factors similar to that performed by
nationally recognized statistical rating organizations in evaluating the credit
quality of a municipal lease obligation, including (i) whether the lease can be
cancelled; (ii) if applicable, what assurance there is that the assets
represented by the lease can be sold; (iii) the strength of the lessee's
general credit (e.g., its debt, administrative, economic and financial
characteristics); (iv) the likelihood that the municipality will discontinue
appropriating funding for the leased property because the property is no longer
deemed essential to the operations of the municipality (e.g., the potential for
an event of nonappropriation); and (v) the legal recourse in the event of
failure to appropriate; and (4) any other factors unique to municipal lease
obligations as determined by the Investment Adviser.

     FUND CHARACTERISTICS AND OTHER POLICIES.  The Fund may engage in
short-term trading consistent with its investment objective.  Securities may be
sold in anticipation of a market decline (a rise in interest rates) or
purchased in anticipation of a market rise (a decline in interest rates).  In
addition, a security may be sold and another security of comparable quality
purchased at approximately the same time to take advantage of what the
Investment Adviser believes to be a


                                      -4-
<PAGE>   112
temporary disparity in the normal yield relationship between the two
securities.  These yield disparities may occur for reasons not directly related
to the investment quality of particular issues or the general movement of
interest rates, such as changes in the overall demand for, or supply of,
various types of tax-exempt securities.

     In general, purchases and sales may also be made to restructure the
portfolio in terms of average maturity, quality, coupon yield or
diversification for any one or more of the following purposes: (a) to increase
income, (b) to improve portfolio quality, (c) to minimize capital depreciation,
(d) to realize gains or losses, or (e) for such other reasons as the Investment
Adviser deems relevant in light of economic market conditions.

     The Fund is a "diversified" management investment company under the
Investment Company Act of 1940 (the "Act").  This means that with respect to
75% of its total assets: (1) the Fund may not invest more than 5% of its total
assets in the securities of any one issuer other than U.S. government
securities and securities of other investment companies and (2) the Fund may
not own more than 10% of the outstanding voting securities of any one issuer.
In applying these limitations, a guarantee of a security will not be considered
a security of the guarantor, provided that the value of all securities issued
or guaranteed by that guarantor, and owned by the Fund, does not exceed 10% of
Fund's total assets.  Since Municipal Obligations ordinarily purchased by the
Fund are not voting securities (notwithstanding the 75% limitation described
above), there is generally no limit on the percentage of a single issuer's
obligations which the Fund may own so long as it does not invest more than 5%
of its total assets in the securities of that issuer.  Consequently, the Fund
may invest in a greater percentage of the outstanding securities of a single
issuer than would an investment company which invests in voting securities.  In
determining the issuer of a security, each state and each political subdivision
agency, and instrumentality of each state and each multi-state agency of which
such state is a member is a separate issuer.  Where securities are backed only
by assets and revenues of a particular instrumentality, facility or
subdivision, such entity is considered the issuer.


                          CERTAIN INVESTMENT PRACTICES

     LENDING OF PORTFOLIO SECURITIES.  In order to generate additional income,
the Fund may, from time to time, lend securities from its portfolios to
brokers, dealers and financial institutions such as banks and trust companies.
Such loans will be secured by collateral consisting of cash or U.S. Government
securities which will be maintained in an amount equal to at least 100% of the
current market value of the loaned securities.  During the period of the loan,
the Fund will receive the income on both the loaned securities and the
collateral and thereby increase its return.  Cash collateral will be invested
in short-term high quality debt securities, which will increase the current
income of the Fund.  The loans will be terminable by the Fund at any time and
by the borrower on one day's notice.  The Fund will have the right to regain
record ownership of loaned securities to exercise beneficial rights such as
rights to interest or other distributions or voting rights on important issues.
The Fund may pay reasonable fees to persons unaffiliated with the Fund for
services in arranging such loans.  Lending of portfolio securities involves a
risk of failure by the borrower to return the loaned securities, in which event
the Fund may incur a loss.

     WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES.  The Fund may purchase
securities on a when-issued or forward commitment basis.  "When-issued" refers
to securities whose terms are available and for which a market exists, but
which have not been issued.  The Fund will engage in when-issued transactions
with respect to securities purchased for its portfolio in order to obtain what
is considered to be an advantageous price and yield at the time of the
transaction.  For when-issued transactions, no payment is made until delivery
is due, often a month or more after


                                      -5-
<PAGE>   113
the purchase.  In a forward commitment transaction, the Fund contracts to
purchase securities for a fixed price at a future date beyond customary
settlement time.

     When the Fund engages in forward commitment and when-issued transactions,
it relies on the seller to consummate the transaction.  The failure of the
issuer or seller to consummate the transaction may result in the Fund losing
the opportunity to obtain a price and yield considered to be advantageous.  The
purchase of securities on a when-issued and forward commitment basis also
involves a risk of loss if the value of the security to be purchased declines
prior to the settlement date.

     On the date the Fund enters into an agreement to purchase securities on a
when-issued or forward commitment basis, the Fund will segregate in a separate
account cash or liquid, high grade debt securities equal in value to the Fund's
commitment.  These assets will be valued daily at market, and additional cash
or securities will be segregated in a separate account to the extent that the
total value of the assets in the account declines below the amount of the
when-issued commitments.  Alternatively, the Fund may enter into offsetting
contracts for the forward sale of other securities that it owns.

     REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements.  A
repurchase agreement is a contract under which the Fund would acquire a
security for a relatively short period (generally not more than 7 days) subject
to the obligation of the seller to repurchase and the Fund to resell such
security at a fixed time and price (representing the Fund's cost plus
interest).  The Fund will enter into repurchase agreements only with member
banks of the Federal Reserve System and with securities dealers.  The
Investment Adviser will continuously monitor the creditworthiness of the
parties with whom the Fund enters into repurchase agreements.  The Fund has
established a procedure providing that the securities serving as collateral for
each repurchase agreement must be delivered to the Fund's custodian either
physically or in book-entry form and that the collateral must be marked to
market daily to ensure that each repurchase agreement is fully collateralized
at all times.  In the event of bankruptcy or other default by a seller of a
repurchase agreement, the Fund could experience delays in liquidating the
underlying securities and could experience losses, including the possible
decline in the value of the underlying securities during the period which the
Fund seeks to enforce its rights thereto, possible subnormal levels of income
and lack of access to income during this period, and the expense of enforcing
its rights.

     The Fund is permitted to engage in certain hedging techniques involving
options and futures transactions in order to reduce the effect of interest rate
movements affecting the market values of the investments held, or intended to
be purchased, by the Fund.

     OPTIONS ON DEBT SECURITIES.  The Fund may purchase and write put and call
options on debt securities which are traded on a national securities exchange
(an "Exchange") to protect its holdings in municipal bonds against a
substantial decline in market value.  Securities are considered related if
their price movements generally correlate to one another.  The purchase of put
options on debt securities which are related to securities held in its
portfolio will enable the Fund to protect, at least partially, unrealized gains
in an appreciated security in its portfolio without actually selling the
security.  In addition, the Fund may continue to receive tax-exempt interest
income on the security.  However, under certain circumstances the Fund may not
be treated as the tax owner of a security held subject to a put option, in
which case interest with respect to such security would  not be tax-exempt for
the Fund.  The purchase of call options on debt securities may help to protect
against substantial increases in prices of securities the Fund intends to
purchase pending its ability to invest in such securities in an orderly manner.



                                      -6-
<PAGE>   114
     The Fund may sell put and call options it has previously purchased, which
could result in a net gain or loss depending on whether the amount realized on
the sale is more or less than the premium and other transaction costs paid in
connection with the option which is sold.

     In order to protect partially against declines in the value of its
portfolio securities, the Fund may sell (write) call options on debt
securities.  A call option gives the purchaser of such option in return for a
premium paid, the right to buy, and the seller has the obligation to sell, the
underlying security at the exercise price if the option is exercised during the
option period.  The writer of the call option who receives the premium has the
obligation to sell the underlying security to the purchaser at the exercise
price during the option period if assigned an exercise notice.  The Fund will
write call options only on a covered basis, which means that it will own the
underlying security subject to a call option at all times during the option
period.  The exercise price of a call option may be below, equal to or above
the current market value of the underlying security at the time the option is
written.

     During the option period, a covered call option writer may be assigned an
exercise notice by the broker/dealer through whom such call option was sold
requiring the writer to deliver the underlying security against payment of the
exercise price.  This obligation is terminated upon the expiration of the
option period or at such earlier point in time when the writer effects a
closing purchase transaction.

     Closing purchase transactions will ordinarily be effected to realize a
profit on an outstanding call option, to prevent an underlying security from
being called, in conjunction with the sale of the underlying security or to
enable the Fund to write another call option on the underlying security with a
different exercise price or different expiration date or both.

     The Fund will write cash secured put options in order to facilitate its
ability to purchase a security at a price lower than the current market price
of such security.  The Fund will write put options only on a "cash secured"
basis which means that if the Fund writes a "put" it will segregate cash
obligations in the event the "put" is exercised.  "Puts" will only be written
in furtherance of the basic investment objectives of the Fund relating to the
acquisition of tax exempt securities and will not be written with the primary
intent of generating income from premiums paid to the Fund in connection with
the sale of the "put".

     The purchase and writing of put and call options involves certain risks.
During the option period, the covered call writer has, in return for the
premium on the option, given up the opportunity to profit from a price increase
in the underlying securities above the exercise price, but, as long as its
obligation as a writer continues, has retained the risk of loss in the event
the price of the underlying security declines.  A secured put writer assumes
the risk that the underlying security will fall below the exercise price in
which case the writer could be required to purchase the security at a higher
price than the then current market price of the security.  In either instance,
the writer has no control over the time when it may be required to fulfill its
obligation as a writer of the option.  Once an option writer has received an
exercise notice, it cannot effect a closing purchase transaction in order to
terminate its obligation under the option and must deliver the underlying
securities, in the case of a call, or acquire the contract securities, in the
case of a put, at the exercise price.  If a put or call option purchased by the
Fund is not sold when it has remaining value, and if the market price of the
underlying security remains equal to or greater than the exercise price, in the
case of a put, or equal to or less than the exercise price, in the case of a
call, the Fund will lose its entire investment in the option.  Also, where a
put or a call option on a particular security is purchased to hedge against
price movements in a related security, the price of the put or call option may
move more or less than the price of the related security.



                                      -7-
<PAGE>   115
     The Fund will not invest in a put or a call option if as a result the
amount of premiums paid for such options then outstanding, when added to the
premiums paid for financial and index futures and put and call options on such
futures, would exceed 10% of the Fund's total assets.

     FUTURES CONTRACTS AND RELATED OPTIONS.  The Fund may engage in the
purchase and sale of interest rate futures contracts ("financial futures") and
tax-exempt bond index futures contracts ("index futures") and the purchase and
writing of put and call options thereon, as well as put and call options on
tax-exempt bond indexes (if and when they are traded) only as a hedge against
changes in the general level of interest rates in accordance with strategies
more specifically described below.

     The purchase of a financial futures contract obligates the buyer to accept
and pay for the specific type of debt security called for in the contract at a
specified future time and at a specified price.  The Fund would purchase a
financial futures contract when it is not fully invested in long-term debt
securities but wishes to defer its purchases for a time until it can invest in
such securities in an orderly manner or because short-term yields are higher
than long-term yields.  Such purchases would enable the Fund to earn the income
on a short-term security while at the same time minimizing the effect of all or
part of an increase in the market price of the long-term debt security which
the Fund intends to purchase in the future.  A rise in the price of the
long-term debt security prior to its purchase either would generally be offset
by an increase in the value of the futures contract purchased by the Fund or
avoids by taking delivery of the debt securities under the futures contract.

     The sale of a financial futures contract obligates the seller to deliver
the specific type of debt security called for in the contract at a specified
future time and at a specified price.  The Fund would sell a financial futures
contract in order to continue to receive the income from a long-term debt
security, while endeavoring to avoid part or all of the decline in market value
of that security which would accompany an increase in interest rates.  If
interest rates did rise, a decline in the value of the debt security held by
the Fund would be substantially offset by an increase in the value of the
futures contract sold by the Fund.  While the Fund could sell a long-term debt
security and invest in a short-term security, ordinarily the Fund would give up
income on its investment, since long-term rates normally exceed short-term
rates.

     In addition, the Fund may purchase and write put and call options on
financial futures contracts which are traded on an Exchange or a Board of Trade
and enter into closing transactions with respect to such options to terminate
an existing position.  Options on financial futures contracts are similar to
options on securities except that a put option on a financial futures contract
gives the purchaser the right in return for the premium paid to assume a short
position in a financial futures contract and a call option on a financial
futures contract gives the purchaser the right in return for the premium paid
to assume a long position in a financial futures contract.

     The Fund anticipates purchasing and selling tax-exempt bond index futures
as a hedge against changes in the market value of the tax exempt bonds which it
holds.  A tax-exempt bond index fluctuates with changes in the market values of
the tax-exempt bonds included in the index.  An index future has similar
characteristics to a financial future except that settlement is made through
delivery of cash rather than the underlying securities.  The sale of an index
future obligates the seller to deliver at settlement an amount of cash equal to
a specified dollar amount multiplied by the difference between the value of the
index at the close of the last trading day of the contract and the price at
which the future was originally written.

     The Fund may also purchase and write put and call options on tax-exempt
bond indexes (if and when such options are traded) and enter into closing
transactions with respect to such options.


                                      -8-
<PAGE>   116
An option on an index future is similar to an option on a debt security except
that an option on an index future gives the holder the right to assume a
position in an index future.  The Fund will use options on futures contracts
and options on tax-exempt bond indexes (if and when they are traded) in
connection with hedging strategies.  Generally, these strategies would be
employed under the same market conditions in which the Fund would use put and
call options on debt securities.

     The Fund may hedge up to the full value of its portfolio through the use
of options and futures.  At the time the Fund purchases a futures contract, an
amount of cash or U.S. Government securities at least equal to the market value
of the futures contract will be deposited in a segregated account with the
Fund's Custodian to collateralize the position and thereby insure that such
futures contract is unleveraged.  The Fund may not purchase or sell futures
contracts or purchase or write related put or call options if immediately
thereafter the sum of the amount of margin deposits on the Fund's existing
futures and related options positions and the amount of premiums paid for
related options (measured at the time of investment) would exceed 5% of the
Fund's total assets.

     While the Fund's hedging transactions may protect the Fund against adverse
movements in the general level of interest rates, such transactions could also
preclude the opportunity to benefit from favorable movements in the level of
interest rates.  Due to the imperfect correlation between movements in the
prices of futures contracts and movements in the prices of the related
securities being hedged, the price of a futures contract may move more than or
less than the price of the securities being hedged.  There is an increased
likelihood that this will occur when a tax-exempt security is hedged by a
futures contract on a taxable security.  Options on futures contracts are
generally subject to the same risks applicable to all option transactions.  In
addition, the Fund's ability to use this technique will depend in part on the
development and maintenance of a liquid secondary market for such options.  For
a discussion of the inherent risks involved with futures contracts and options
thereon, see "Risks Relating to Transactions in Futures Contracts and Related
Options" below.

     The Fund's policies permitting the purchase and sale of futures contracts
and the purchase and writing of related put or call options for hedging
purposes only may not be changed without the approval of shareholders holding a
majority of the Fund's outstanding voting securities.  The Board of Directors
may authorize procedures, including numerical limitations, with regard to such
transactions in furtherance of the Fund investment objectives.  Such procedures
are not deemed to be fundamental and may be changed by the Board of Trustees
without the vote of the Fund's shareholders.

     RISKS RELATING TO TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.
Positions in futures contracts may be closed out only on an exchange or board
of trade which provides a market for such futures.  Although the Fund intends
to purchase or sell futures contracts only on exchanges or boards of trade
where there appears to be an active market, there is no assurance that a liquid
market on an exchange or board of trade will exist for any particular contract
or at any particular time.  In the event a liquid market does not exist, it may
not be possible to close a futures position, and in the event of adverse price
movements, the Fund would continue to be required to make daily cash payments
of maintenance margin.  In addition, limitations imposed by an exchange or
board of trade on which futures contracts are traded may compel or prevent the
Fund from closing out a contract which may result in reduced gain or increased
loss to the Fund.  The absence of a liquid market in futures contracts might
cause the Fund to make or take delivery of the underlying securities at a time
when it may be disadvantageous to do so.  The purchase of put options on
futures contracts involves less potential dollar risk to the Fund than an
investment of equal amount in futures contracts, since the premium is the
maximum amount of risk the



                                      -9-
<PAGE>   117
purchaser of the option assumes.  The entire amount of the premium paid for an
option can be lost by the purchaser, but no more than that amount.


                            INVESTMENT RESTRICTIONS

     The Fund has adopted certain fundamental investment restrictions upon its
investments as set forth below which may not be changed without the approval of
the holders of a majority of the outstanding shares of the Fund.  A majority
for this purpose means: (a) more than 50% of the outstanding shares of the Fund
or (b) 67% or more of the shares represented at a meeting where more than 50%
of the outstanding shares of the Fund are represented, whichever is less.
Under these restrictions, the Fund may not:

     1.   Borrow money except from banks for temporary or emergency (not
          leveraging) purposes, including the meeting of redemption requests
          that might otherwise require the untimely disposition of securities,
          in an amount up to 15% of the value of the Fund's total assets
          (including the amount borrowed) valued at market less liabilities
          (not including the amount borrowed) at the time the borrowings was
          made.  While borrowing exceed 5% of the value of the Fund's total
          assets, the Fund will not purchase any additional securities.
          Interest paid on borrowing will reduce the Fund's net investment
          income.

     2.   Pledge, hypothecate, mortgage or otherwise encumber its assets,
          except in an amount up to 10% of the value of its total assets but
          only to secure borrowing for temporary or emergency purposes or as
          may be necessary in connection with maintaining collateral in
          connection with writing put and call options or making initial margin
          deposits in connection with the purchase or sale of financial
          futures, index futures contracts and related options.

     3.   With respect to 75% of its total assets, purchase securities (other
          than obligations issued or guaranteed by the United States
          government, its agencies of instrumentalities and shares of other
          investment companies) of any issuer if the purchase would cause
          immediately thereafter more than 5% of the value of the Fund's total
          assets invested in the securities of such issuer or the Fund would
          own more than 10% of the outstanding voting securities of such
          issuer.

     4.   Make loans to others, except through the purchase of obligations in
          which the Fund is authorized to invest, entering in repurchase
          agreements and lending portfolio securities in an amount not
          exceeding one third of its total assets.

     5.   Purchase illiquid securities, including securities subject to
          restrictions on disposition under the Securities Act of 1933,
          repurchase agreements maturing in more than seven days, and
          securities which do not have readily available market quotations, if
          such purchase would cause the Fund to have more than 10% of its net
          assets invested in such types of securities.

     6.   Purchase or retain the securities of any issuer, if those officers
          and Trustees of the Fund or the Investment Adviser who own
          beneficially more than of 1% of the securities of such issuer,
          together own more than 5% of the securities of such issuer.




                                      -10-
<PAGE>   118
     7.   Write, purchase or sell puts, calls or combinations thereof, except
          put and call options on debt securities, futures contracts based on
          debt securities, indices of debt securities and futures contracts
          based on indices of debt securities, sell securities on margin or
          make short sales of securities or maintain a short position, unless
          at all times when a short position is open it owns an equal amount of
          such securities or securities convertible into or exchangeable,
          without payment of any further consideration, for securities of the
          same issue as, and equal in amount to, the securities sold short, and
          unless not more than 10% of the Fund's net assets (taken at current
          value) is held as collateral for such sales at any one time.

     8.   Underwrite the securities of other issuers, except insofar as the
          Fund may be deemed an underwriter under the Securities Act of 1933 in
          disposing of a portfolio security.

     9.   Purchase or sell real estate, real estate investment trust
          securities, commodities or commodity contracts, except commodities
          and commodities contracts which are necessary to enable the Fund to
          engage in permitted futures and options transactions necessary to
          implement hedging strategies, or oil and gas interests.  This
          limitation shall not prevent the Fund from investing in municipal
          securities secured by real estate or interests in real estate or
          holding real estate acquired as a result of owning such municipal
          securities.

     10.  Invest in common stock or in securities of other investment
          companies, except that securities of investment companies may be
          acquired as part of a merger, consolidation or acquisition of assets
          and units of registered unit investment trusts whose assets consist
          substantially of tax-exempt securities may be acquired to the extent
          permitted by Section 12 of the Act or applicable rules.

     11.  Invest more than 25% of its assets in the securities of "issuers" in
          any single industry; provided that there shall be no limitation on
          the purchase of obligations issued or guaranteed by the United States
          Government, its agencies or instrumentalities or by any state or
          political subdivision thereof.  For purposes of this limitation when
          the assets and revenues of an agency, authority, instrumentality or
          other political subdivision are separate from those of the government
          creating the issuing entity and a security is backed only by the
          assets and revenues of the entity, the entity would be deemed to be
          the sole issuer of the security.  Similarly, in the case of an
          industrial development or pollution control bond, if that bond is
          backed only by the assets and revenues of the nongovernmental user,
          then such nongovernmental user would be deemed to be the sole issuer.
          If, however, in either case, the creating government or some other
          entity guarantees a security, such a guarantee would be considered a
          separate security and would be treated as an issue of such government
          or other entity unless all securities issued or guaranteed by the
          government or other entity owned by the Fund does not exceed 10% of
          the Fund's total assets.

     12.  Invest more than 5% of its total assets in securities of any issuers
          if the party responsible for payment, together with any predecessor,
          has been in operation for less than three years (except U.S.
          government and agency obligations and obligations backed by the
          faith, credit and taxing power of any person authorized to issue tax
          exempt securities).




                                      -11-
<PAGE>   119
     13.  Issue any senior securities, except insofar as the Fund may be deemed
          to have issued a senior security by: entering into a repurchase
          agreement; purchasing securities in a when-issued or delayed delivery
          basis; purchasing or selling any options or financial futures
          contract; borrowing money or lending securities in accordance with
          applicable investment restrictions.

     In order to comply with certain state regulatory policies, the Fund has
adopted a non- fundamental policy prohibiting the purchase of warrants.  The
Fund's Board of Trustees has approved the following non-fundamental investment
policy pursuant to an order of the SEC: Notwithstanding any investment
restriction to the contrary, the Fund may, in connection with the John Hancock
Group of Funds Deferred Compensation Plan for Independent Trustees/Directors,
purchase securities of other investment companies within the John Hancock Group
of Funds provided that, as a result, (i) no more than 10% of the Fund's assets
would be invested in securities of all other investment companies, (ii) such
purchase would not result in more than 3% of the total outstanding voting
securities of any one such investment company being held by the Fund and (iii)
no more than 5% of the Fund's assets would be invested in any one such
investment company.

                     INVESTMENT ADVISORY AND OTHER SERVICES

     As described in the Prospectus, the Fund receives its investment advice
from the Investment Adviser.  Investors should refer to the Prospectus for a
description of certain information concerning the investment management
contract.  Each of the Trustees and principal officers of the Fund who is also
an affiliated person of the Investment Adviser is named above, together with the
capacity in which such person is affiliated with the Fund and the Investment
Adviser.
     The Investment Adviser, located at 101 Huntington Avenue, Boston,
Massachusetts 02199-7603, was organized in 1968 and has more than $13 billion in
assets under management in its capacity as investment adviser to the Fund and
the other mutual funds and publicly traded investment companies in the John
Hancock group of funds having a combined total of over 1,060,000 shareholders.
The Investment Adviser is a wholly-owned subsidiary of The Berkeley Financial
Group, which is in turn a wholly-owned subsidiary of John Hancock Subsidiaries,
Inc., which is in turn a wholly-owned subsidiary of John Hancock Mutual Life
Insurance Company (the "Life Company"), one of the nation's oldest and largest
financial services companies.  With total assets under management of over $80
billion, the Life Company is one of the ten largest life insurance companies in
the United States, and carries Standard & Poor's and A.M. Best's highest
ratings.  Founded in 1862, the Life Company has been serving clients for over
130 years.

     As described in the Prospectus under the caption, "Organization and
Management of the Fund," the Fund has entered into an investment management
contract with the Investment Adviser.  Under the investment management contract,
the Investment Adviser provides the Fund with (i) a continuous investment
program, consistent with the Fund's stated investment objective and policies,
(ii) supervision of all aspects of the Fund's operations except those that are
delegated to a custodian, transfer agent or other agent and (iii) such
executive, administrative and clerical personnel, officers and equipment as are
necessary for the conduct of its business.  The Investment Advisor is
responsible for the management of the Fund's portfolio assets.

     No person other than the Investment Adviser, its directors and employees
regularly furnishes advice to the Fund with respect to the desirability of the
Fund investing in, purchasing or selling securities.  The Investment Adviser may
from time to time receive statistical or other similar factual information, and
information regarding general economic factors and trends, from the Life Company
and its affiliates.

     Under the terms of the investment management contract with the Fund, the
Investment Adviser provides the Fund with office space, equipment and supplies
and other facilities and personnel required for the business of the Fund.  The
Investment Adviser pays the compensation of all officers and employees of the
Fund and Trustees of the Fund affiliated with the Investment Adviser, the office
expenses of the Fund, including those of the Fund's Treasurer and Secretary, and
other expenses incurred by the Investment Adviser in connection with the
performance of its duties.  All expenses which are not specifically paid by the
Investment Adviser and which are incurred in the operation of the Fund
including, but not limited to, (i) the fees of the Trustees of the Fund who are
not "interested persons," as such term is defined in the 1940 Act (the
"Independent Trustees"), (ii) the fees of the members of the Fund's Advisory
Board (described above) and (iii) the continuous public offering of the shares
of the Fund are borne by the Fund.

     As provided by the investment management contract, the Fund pays the
Investment Adviser an investment management fee, which is accrued daily and paid
monthly in arrears, equal on an annual basis to a 0.55% of the Fund's average
daily net asset value.



                                      -17-
<PAGE>   125
     The Investment Adviser may voluntarily and temporarily reduce its advisory
fee or make other arrangements to limit the Fund's expenses to a specified
percentage of average daily net assets.  The Investment Adviser retains the
right to re-impose the advisory fee and recover any other payments to the extent
that, at the end of any fiscal year, the Fund's annual expenses fall below this
limit.

     In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of any state limit where the
Fund is registered to sell shares of beneficial interest, the fee payable to the
Investment Adviser will be reduced to the extent required by law.  At this time,
the most restrictive limit on expenses imposed by a state requires that expenses
charged to the Fund in any fiscal year not exceed 2.5% of the first $30,000,000
of the Fund's average daily net asset value, 2% of the next $70,000,000 and 1.5%
of the remaining average daily net asset value.  When calculating the limit
above, the Fund may exclude interest, brokerage commissions and extraordinary
expenses.

     Pursuant to the investment management contract, the Investment Adviser is
not liable to the Fund or its shareholders for any error of judgment or mistake
of law or for any loss suffered by the Fund in connection with the matters to
which its contract relates, except a loss resulting from willful misfeasance,
bad faith or gross negligence on the part of the Investment Adviser in the
performance of its duties or from its reckless disregard of the obligations and
duties under the contract.

     The investment management contract initially expires on December
22, 1996, and will continue in effect from year to year thereafter if
approved annually by a vote of a majority of the Trustees of the Fund
who are not interested persons of one or more of the parties to the
contract, cast in person at a meeting called for the purpose of voting
on such approval, and by either a majority of the Trustees or the
holders of a majority of the Fund's outstanding voting securities.
The management contract may, on 60 days' written notice, be terminated
at any time without the payment of any penalty by the Fund by vote of
a majority of the outstanding voting securities of the Fund, by the
Trustees or by the Investment Adviser.  The management contract
terminates automatically in the event of its assignment.

     Securities held by the Fund may also be held by other funds or
investment advisory clients for which the Investment Adviser or its
affiliates provide investment advice.  Because of different investment
objectives or other factors, a particular security may be bought for
one or more funds or clients when one or more are selling the same
security.  If opportunities for purchase or sale of securities by the
Investment Adviser or for other funds or clients for which the
Investment Adviser renders investment advice arise for consideration
at or about the same time, transactions in such securities will be
made, insofar as feasible, for the respective funds or clients in a
manner deemed equitable to all of them.  To the extent that
transactions on behalf of more than one client of the Investment
Adviser or its respective affiliates may increase the demand for
securities being purchased or the supply of securities being sold,
there may be an adverse effect on price.

     Under the investment management contract, the Fund may use the
name "John Hancock" or any name derived from or similar to it only for
so long as the investment management contract or any extension,
renewal or amendment thereof remains in effect.  If the Fund's
investment management contract is no longer in effect, the Fund (to
the extent that it lawfully can) will cease to use such name or any
other name indicating that it is advised by or otherwise connected
with the Investment Adviser.  In addition, the Investment Adviser or
the Life Company may grant the non-exclusive right to use the name
"John Hancock" or any similar name to any other corporation or entity,
including but not limited to any investment company of which the Life
Company or any



                                      -18-
<PAGE>   126
subsidiary or affiliate thereof or any successor to the business of any
subsidiary or affiliate thereof shall be the investment adviser.

    For the fiscal years ended December 31, 1992, 1993 and 1994 advisory fees
payable by the Fund to TFMC, the Fund's former investment adviser, amounted to
$515,297, $888,791 and $1,136,532, respectively; however, a portion of such fees
were not imposed pursuant to the voluntary fee and expense assumption and fee
waiver then in effect (see "The Fund's Expenses" in the Prospectus). For the
period from December 22, 1994 to December 31, 1994, advisory fees payable by the
Fund were paid to the Investment Adviser.

    ADMINISTRATIVE SERVICES AGREEMENT. The Fund was a party to an administrative
services agreement with TFMC (the "Services Agreement"), pursuant to which TFMC
performed bookkeeping and accounting services and functions, including preparing
and maintaining various accounting books, records and other documents and
keeping such general ledgers and portfolio accounts as are reasonably necessary
for the operation of the Fund. Other administrative services included
communications in response to shareholder inquiries and certain printing
expenses of various financial reports. In addition, such staff and office space,
facilities and equipment was provided as necessary to provide administrative
services to the Fund. The Services Agreement was amended in connection with the
appointment of the Investment Adviser as adviser to the Fund to permit services
under the Agreement to be provided to the Fund by the Investment Adviser and its
affiliates. The Services Agreement was terminated during the current fiscal
year.
    For the fiscal years ended December 31, 1992, 1993 and 1994, the Fund paid
to TFMC (pursuant to the Services Agreement) $68,225, $94,272 and $116,742,
respectively, of which $43,681, $62,855 and $81,515, respectively, was paid to
TFMC and $24,544, $31,417 and $35,227, respectively, were paid for certain data
processing and pricing information services.
                              DISTRIBUTION CONTRACT

    As discussed in the Prospectus, the Fund's shares are sold on a continuous
basis at the public offering price. The Distributor, a wholly-owned subsidiary
of the Investment Adviser, has the exclusive right, pursuant to the Distribution
Agreement dated December 22, 1994 (the "Distribution Agreement"), to purchase
shares from the Fund at net asset value for resale to the public or to
broker-dealers at the public offering price. Upon notice to all broker-dealers
("Selling Brokers") with whom it has sales agreements, the Distributor may allow
such Selling Brokers up to the full applicable sales charge during periods
specified in such notice. During these periods, such Selling Brokers may be
deemed to be underwriters as that term is defined in the Securities Act of 1933.

    The Distribution Agreement was initially adopted by the affirmative vote of
the Fund's Board of Trustees including the vote a majority of Trustees who are
not parties to the agreement or interested persons of any such party, cast in
person at a meeting called for such purpose. The Distribution Agreement shall
continue in effect until December 22, 1994 and from year to year if approved by
either the vote of the Fund's shareholders or the Board of Trustees including
the vote of a majority of Trustees who are not parties to the agreement or
interest persons of any such





                                      -19-
<PAGE>   127
party, cast in person at a meeting called for such purpose. The Distribution
Agreement may be terminated at any time, without penalty, by either party upon
sixty (60) days' written notice or by a vote of a majority of the outstanding
voting securities of the Fund and terminates automatically in the case of an
assignment by the Distributor.

    Total underwriting commissions for sales of the Fund's Class A Shares for
the fiscal years ended December 31, 1992, 1993 and 1994, respectively, were
$1,430,272, $1,224,810 and $149,847, respectively. Of such amounts $121,373,
$108,653 and $47,967, respectively, were retained by the Fund's former
distributor, Transamerica Fund Distributors, Inc. and the remainder was
reallowed to dealers. For the period from December 22, 1994 to December 31,
1994, underwriting commissions were paid to the Distributor.

    DISTRIBUTION PLAN. The Board of Trustees, including the Independent Trustees
of the Fund, approved new distribution plans pursuant to Rule 12b-1 under the
1940 Act for Class A Shares ("Class A Plan") and Class B Shares ("Class B
Plan"). Such Plans were approved by a majority of the outstanding shares of each
respective class on December 16, 1994 and became effective on December 22, 1994.
    Under the Class A Plan, the distribution or services fee will not exceed an
annual rate of 0.15% of the average daily net asset value of the Class A Shares
of the Fund (determined in accordance with such Fund's Prospectus as from time
to time in effect). Any expenses under the Class A Plan not reimbursed within 12
months of being presented to the Fund for repayment are forfeited and not
carried over to future years. Under the Class B Plan, the distribution or
services fee to be paid by the Fund will not exceed an annual rate of 1.00% of
the average daily net assets of the Class B Shares of the Fund (determined in
accordance with such Fund's prospectus as from time to time in effect); provided
that the portion of such fee used to cover Service Expenses (described below)
shall not exceed an annual rate of 0.25% of the average daily net asset value of
the Class B Shares of the Fund. The Distributor has agreed to limit the payment
of expenses pursuant to the Class B Plan to 0.90% of the average daily net
assets of the Class B Shares of the Fund. Under the Class B Plan, the fee covers
the Distribution and Service Expenses (described below) and interest expenses on
unreimbursed distribution expenses. In accordance with generally accepted
accounting principles, the Fund does not treat distribution fees in excess of
0.75% of the Fund's net assets attributable to Class B shares as a liability of
the Fund and does not reduce the current net assets of Class B by such amount
although the amount may be payable in the future.
    Under the Plans, expenditures shall be calculated and accrued daily and paid
monthly or at such other intervals as the Trustees shall determine. The fee may
be spent by the Distributor on Distribution Expenses or Service Expenses.
"Distribution Expenses" include any activities or expenses primarily intended to
result in the sale of shares of the relevant class of the Fund, including, but
not limited to: (i) initial and ongoing sales compensation payable out of such
fee as such compensation is received by the Distributor or by Selling Brokers,
(ii) direct out-of-pocket expenses incurred in connection with the distribution
of shares, including expenses related to printing of prospectuses and reports;
(iii) preparation, printing and distribution of sales literature and advertising
material; (iv) an allocation of overhead and other branch office expenses of the
Distributor related to the distribution of Fund Shares (v) distribution expenses
that were incurred by the Fund's former distributor and not recovered through
payments under the Class A or Class B former plans or through receipt of
contingent deferred sales charges; and (vi) in the event that any other
investment company (the "Acquired Fund") sells all or substantially all of its
assets, merges or otherwise engages in a combination with the Fund, distribution
expenses originally incurred in connection with the distribution of the Acquired
Fund's shares. Service Expenses under the Plans include payments made to, or on
account of, account executives of selected


                                      -20-
<PAGE>   128
broker-dealers (including affiliates of the Distributor) and others who furnish
personal and shareholder account maintenance services to shareholders of the
relevant class of the Fund.

    During the fiscal year ended December 31, 1994, total payments made by the
Fund under the former Class A Rule 12b-1 plan to the former distributor amounted
to $200,118, and of such amount $417, $2,068, $555, $26,800 and $170,278
represented payments for (1) the cost of printing and distribution prospectuses
and financial reports to investors, (2) various sales literature, (3)
advertising expenses, (4) distribution and/or administrative services and (5)
service fees, respectively. During the period from December 22, 1994 to December
31, 1994, payment under the Class A Plan was made to the Distributor.

    During the fiscal year ended December 31, 1994, total payments made by the
Fund under the former Class B Rule 12b-1 plan to the former distributor amounted
to $658,933 of which:

**       (1)       $109,829 represented service fees which were comprised of
                   $29,408 for distribution and/or administrative services
                   provided by the Fund's former distributor and $80,421 for
                   service fees paid to broker/dealers.

         (2)       $549,104 represented as the total of distribution fees paid
                   to the former distributor which are comprised of:

                   a)        $232,594 for dealer commission payments; 

                   b)        $58,148 for underwriting fees; and

                   c)        $258,362 for interest or the carrying charges.

    For the fiscal year ended December 31, 1994, the former distributor received
$209,200 in contingent deferred sales charges from redemption of the Fund's
Class B shares. For the period from December 22, 1994 to December 31, 1994, the
Distributor received fees under the Class B Plan and contingent deferred sales
charges from redemptions of Class B shares.

    Each of the Plans provides that it will continue in effect only so long as
its continuance is approved at least annually by a majority of both the Trustees
and the Independent Trustees. Each of the Plans provides that it may be
terminated (a) at any time by vote of a majority of the Trustees, a majority of
the Independent Trustees, or a majority of the respective Class' outstanding
voting securities or (b) by the Distributor on 60 days' notice in writing to the
Fund. Each of the Plans further provides that it may not be amended to increase
the maximum amount of the fees for the services described therein without the
approval of a majority of the outstanding shares of the class of the Fund which
has voting rights with respect to the Plan. Each of the Plans provides that no
material amendment to the Plan will, in any event, be effective unless it is
approved by a majority vote of the Trustees and the Independent Trustees of the
Fund. The holders of Class A Shares and Class B Shares have exclusive voting
rights with respect to the Plan applicable to their respective class of shares.
The Board of Trustees, including the Trustees who are not interested in the Fund
and have no direct or indirect interest in the Plans, has determined that, in
their judgment, there is a reasonable likelihood that the Plans will benefit the
holders of the applicable class of shares of the Fund.

    Information regarding the services rendered under the Plans and the
Distribution Agreement and the amounts paid therefore by the respective Class of
the Fund are provided to, and reviewed by, the Board of Trustees on a quarterly
basis. In its quarterly review, the Board of Trustees considers the continued
appropriateness of the Plans and the Distribution Agreement and the level of
compensation provided therein.

<PAGE>   129
                                NET ASSET VALUE

    For purposes of calculating the net asset value ("NAV") of a Fund's shares,
the following procedures are utilized wherever applicable. Debt investment
securities are valued on the basis of valuations furnished by a principal market
maker or a pricing service, both of which generally utilize electronic data
processing techniques to determine valuations for normal institutional size
trading units of debt securities without exclusive reliance upon quoted prices.

    Short-term debt investments which have a remaining maturity of 60 days or
less are generally valued at amortized cost which approximates market value. If
market quotations are not readily available or if in the opinion of the
Investment Adviser any quotation or price is not representative of true market
value, the fair value of the security may be determined in good faith in
accordance with procedures approved by the Trustees. The Fund will not price its
securities on the following national holidays: New Year's Day; President's Day;
Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and
Christmas Day.

                     INITIAL SALES CHARGE ON CLASS A SHARES

    Shares of the Fund are offered at a price equal to their net asset value
plus a sales charge which, at the option of the purchaser, may be imposed either
at the time of purchase (the "initial sales charge alternative") or on a
contingent deferred basis (the "deferred sales charge alternative"). Share
certificates will not be issued unless requested by the shareholder in writing,
and then only will be issued for full shares. The Board of Trustees reserves the
right to change or waive the minimum investment requirements and to reject any
order to purchase shares (including purchase by exchange) when in the judgment
of the Investment Adviser such rejection is in the Fund's best interest.

    INITIAL SALES CHARGE ON CLASS A SHARES. The sales charges applicable to
purchases of Class A Shares of the Fund are described in the Fund's Class A and
Class B Prospectus. Methods of obtaining reduced sales charges referred to
generally in the Prospectus are described in detail below. In calculating the
sales charge applicable to current purchases of Class A Shares, the investor is
entitled to cumulate current purchases with the greater of the current value (at
offering price) of the Class A Shares of the Fund, or if Investor Services is
notified by the investor's dealer or the investor at the time of the purchase,
the cost of the Class A Shares owned.

    COMBINED PURCHASES. In calculating the sales charge applicable to purchases
of Class A Shares made at one time, the purchases will be combined if made by
(a) an individual, his or her spouse and their children under the age of 21
purchasing securities for his or her own account, (b) a trustee or other
fiduciary purchasing for a single trust, estate or fiduciary account and (c)
certain groups of four or more individuals making use of salary deductions or
similar group methods of payment whose funds are combined for the purchase of
mutual fund shares. Further information about combined purchases, including
certain restrictions on combined group purchases, is available from Investor
Services or a Selling Broker's representative.

    WITHOUT SALES CHARGE. As described in the Class A and Class B Prospectus,
Class A shares of the Fund may be sold without a sales charge to certain persons
described in the prospectus.

    ACCUMULATION PRIVILEGE. Investors (including investors combining purchases)
who are already Class A Shareholders may also obtain the benefit of the reduced
sales charge by taking into account not only the amount then being invested but
also the purchase price or value of the Class A Shares already held by such
person.


                                      -22-
<PAGE>   130
    COMBINATION PRIVILEGE. Reduced sales charges (according to the schedule set
forth in the Class A and Class B Prospectus) also are available to an investor
based on the aggregate amount of his concurrent and prior investments in Class A
Shares of the Fund and shares of all other John Hancock funds which carry a
sales charge.

    LETTER OF INTENTION. The reduced sales loads are also applicable to
investments made over a specified period pursuant to a Letter of Intention
(LOI), which should be read carefully prior to its execution by an investor. The
Fund offers two options regarding the specified period for making investments
under the LOI. All investors have the option of making their investments over a
period of thirteen (13) months. Investors who are using the Fund as a funding
medium for a qualified retirement plan, however, may not opt to make the
necessary investments called for by the LOI over a forty-eight (48) month
period. These qualified retirement plans include IRA'S, SEP, SARSEP, TSA, 401
(k) plans, TSA plans and 457 plans. Such an investment (including accumulations
and combinations) must aggregate $50,000 or more invested during the specified
period from the date of the LOI or from a date within ninety (90) days prior
thereto, upon written request to Investor Services. The sales charge applicable
to all amounts invested under the LOI is computed as if the aggregate amount
intended to be invested had been invested immediately. If such aggregate amount
is not actually invested, the difference in the sales charge actually paid and
the sales charge payable had the LOI not been in effect is due from the
investor. However, for the purchases actually made with the specified period
(either 13 or 48 months), the sales charge applicable will not be higher than
that which would have been applied (including accumulations and combinations)
had the LOI been for the amount actually invested.
    The LOI authorizes Investor Services to hold in escrow sufficient Class A
shares (approximately 5%) of the aggregate to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the specified period, at which time
the escrow shares will be released. If the total investment specified in the LOI
is not completed, the Class A shares held in escrow may be redeemed and the
proceeds used as required to pay such sales charges as may be due. By signing
the LOI, the investor authorizes Investor Services to act as his
attorney-in-fact to redeem any escrowed shares and adjust the sales charge, if
necessary. A LOI does not constitute a binding commitment by an investor to
purchase, or by the Fund to sell, any additional shares and may be terminated at
any time.

                     DEFERRED SALES CHARGE ON CLASS B SHARES

    CONTINGENT DEFERRED SALES CHARGE. Investments in Class B shares are
purchased at net asset value per share without the imposition of a sales charge
so that the Fund will receive the full amount of the purchase payment. Class B
Shares which are redeemed within six years of purchase will be subject to a
contingent deferred sales charge ("CDSC") at the rates set forth in the Class A
and Class B Prospectus as a percentage of the dollar amount subject to the CDSC.
The charge will be assessed on an amount equal to the lesser of the current
market value or the original purchase cost of the Class B Shares being redeemed.
Accordingly, no CDSC will be imposed on increases in account value above the
initial purchase prices, including Class B Shares derived from reinvestment of
dividends or capital gains distributions.

    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of Class B Shares until the time of
redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchases of shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month.


                                      -23-
<PAGE>   131
    Proceeds from the CDSC are paid to the Distributor and are used in whole or
in part by the Distributor to defray its expenses related to providing
distribution-related services to the Fund in connection with the sale of the
Class B Shares, such as the payment of compensation to select Selling Brokers
for selling Class B Shares. The combination of the CDSC and the distribution and
service fees facilitates the ability of the Fund to sell the Class B Shares
without a sales charge being deducted at the time of the purchase. See the Class
A and Class B Prospectus for additional information regarding the CDSC.


                               SPECIAL REDEMPTIONS

    Although it is the Fund's present policy to make payment of redemption
proceeds in cash, if the Board of Trustees determines that a material adverse
effect would otherwise be experienced by remaining investors, redemption
proceeds may be paid in whole or in part by a distribution in kind of securities
from the Fund in conformity with rules of the Securities and Exchange
Commission, valuing such securities in the same manner they are valued in
determining NAV, and selecting the securities in such manner as the Board may
deem fair and equitable. If such a distribution occurs, investors receiving
securities and selling them before their maturity could receive less than the
redemption value of such securities and, in addition, could incur certain
transaction costs. Such a redemption is not as liquid as a redemption paid in
cash or federal funds. The Fund has elected to be governed by Rule 18f-1 under
the 1940 Act, pursuant to which the Fund is obligated to redeem shares solely in
cash up to the lesser of $250,000 or 1% of the net asset value of the Fund
during any 90 day period for any one account.


                         ADDITIONAL SERVICES AND PROGRAM

    EXCHANGE PRIVILEGE. As described more fully in the Class A and Class B
Prospectus, the Fund permits exchanges of shares of any class of the Fund for
shares of the same class in any other John Hancock fund offering that class.

    SYSTEMATIC WITHDRAWAL PLAN. As described briefly in the Class A and Class B
Prospectus, the Fund permits the establishment of a Systematic Withdrawal Plan.
Payments under this plan represent proceeds arising from the redemption of Fund
shares. Since the redemption price of Fund shares may be more or less than the
shareholder's cost, depending upon the market value of the securities owned by
the Fund at the time of redemption, the distribution of cash pursuant to this
plan may result in realization of gain or loss for purposes of Federal, state
and local income taxes. The maintenance of a Systematic Withdrawal Plan
concurrently with purchases of additional Class A or Class B Shares of the Fund
could be disadvantageous to a shareholder because of the initial sales charge
payable on such purchases of Class A Shares and the CDSC imposed on redemptions
of Class B Shares and because redemptions are taxable events. Therefore, a
shareholder should not purchase Fund shares at the same time as a Systematic
Withdrawal Plan is in effect. The Fund reserves the right to modify or
discontinue the Systematic Withdrawal Plan of any shareholder on 30 days' prior
written notice to such shareholder, or to discontinue the availability of such
plan in the future. The shareholder may terminate the plan at any time by giving
proper notice to Fund Services.

    MONTHLY AUTOMATIC ACCUMULATION PROGRAM ("MAAP"). This program is explained
fully in the Fund's Class A and Class B Prospectus and the Account Privileges
Application. The program, as it relates to automatic investment checks, is
subject to the following conditions;

    The investments will be drawn on or about the day of the month indicated.


                                      -24-
<PAGE>   132
    The privilege of making investments through the Monthly Automatic
Accumulation Program may be revoked by Investor Services without prior notice if
any investment is not honored by the shareholder's bank. The bank shall be under
no obligation to notify the shareholder as to the non-payment of any check.

    The program may be discontinued by the shareholder either by calling
Investor Services or upon written notice to Investor Services which is received
at least five (5) business days prior to the due date of any investment.

    REINVESTMENT PRIVILEGE. A shareholder who has redeemed Fund shares may,
within 120 days after the date of redemption, reinvest without payment of a
sales charge any part of the redemption proceeds in shares of the same class of
the Fund or another John Hancock mutual fund, subject to the minimum investment
limit in that fund. The proceeds from the redemption of Class A Shares may be
reinvested at net asset value without paying a sales charge in Class A Shares of
the Fund or in Class A Shares of another John Hancock mutual fund. If a CDSC was
paid upon a redemption, a shareholder may reinvest the proceeds from that
redemption at net asset value in additional shares of the class from which the
redemption was made. The shareholder's account will be credited with the amount
of any CDSC charged upon the prior redemption and the new shares will continue
to be subject to the CDSC. The holding period of the shares acquired through
reinvestment will, for purposes of computing the CDSC payable upon a subsequent
redemption, include the holding period of the redeemed shares. The Fund may
modify or terminate the reinvestment privilege at any time.

    A redemption or exchange of Fund shares is a taxable transaction for Federal
income tax purposes. Even if the reinvestment privilege is exercised, and any
gain or loss realized by a shareholder on the redemption or other disposition of
Fund shares will be treated for tax purposes as described under the caption "Tax
Status."


                        DESCRIPTION OF THE FUND'S SHARES

    SHARES OF THE FUND. Ownership of the Fund is represented by transferable
shares of beneficial interest. The Declaration of Trust permits the Trustees to
create an unlimited number of series and classes of shares of the Fund and, with
respect to each series and class, to issue an unlimited number of full or
fractional shares and to divide or combine the shares into a greater or lesser
number of shares without thereby changing the proportionate beneficial interests
of the Fund.

    Each share of each series or class of the Fund represents an equal
proportionate interest with each other in that series or class, none having
priority or preference over other shares of the same series or class. The
interest of investors in the various series or classes of the Fund is separate
and distinct. All consideration received for the sales of shares of a particular
series or class of the Fund, all assets in which such consideration is invested
and all income, earnings and profits derived from such investments will be
allocated to and belong to that series or class. As such, each such share is
entitled to dividends and distributions out of the net income belonging to that
series or class as declared by the Board of Trustees. Shares of the Fund have a
par value of $0.01 per share. The assets of each series are segregated on the
Fund's books and are charged with the liabilities of that series and with a
share of the Fund's general liabilities. The Board of Trustees determines those
assets and liabilities deemed to be general assets or liabilities of the Fund,
and these items are allocated among each series in proportion to the relative
total net assets of each series. In the unlikely event that the liabilities
allocable to a series exceed the assets of that series, all or a portion of such
liabilities may have to be borne by the other series.


                                      -25-
<PAGE>   133
    Pursuant to the Declaration of Trust, the Trustees may authorize the
creation of additional series of shares (the proceeds of which would be invested
in separate, independently managed portfolios) and additional classes within any
series (which would be used to distinguish among the rights of different
categories of shareholders, as might be required by future regulations or other
unforeseen circumstances). As of the date of this Statement of Additional
Information, the Trustees have authorized the issuance of two classes of shares
of the Fund designated as Class A and Class B. Class A and Class B Shares of the
Fund represent an equal proportionate interest in the aggregate net asset values
attributable to that class of the Fund. Holders of Class A Shares and Class B
Shares each have certain exclusive voting rights on matters relating to the
Class A Plan and the Class B Plan, respectively. The different classes of the
Fund may bear different expenses relating to the cost of holding shareholder
meetings necessitated by the exclusive voting rights of any class of shares.

    Dividends paid by the Fund, if any, with respect to each class of shares
will be calculated in the same manner, at the same time and on the same day and
will be in the same amount, except for differences caused by the fact that (i)
Class B Shares will pay higher distribution and service fees than Class A Shares
and (ii) each of Class A Shares and Class B Shares will bear any class expenses
properly allocable to such class of shares, subject to the conditions set forth
in a private letter ruling that the Fund has received from the Internal Revenue
Service relating to its multiple- class structure. Similarly, the net asset
value per share may vary depending whether Class A Shares or Class B Shares are
purchased.

    VOTING RIGHTS. Shareholders are entitled to a full vote for each full share
held. The Trustees themselves have the power to alter the number and the terms
of office of Trustees, and they may at any time lengthen their own terms or make
their terms of unlimited duration (subject to certain removal procedures) and
appoint their own successors, provided that at all times at least a majority of
the Trustees have been elected by shareholders. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees. Although
the Fund need not hold annual meetings of shareholders, the trustees may call
special meetings of shareholders for action by shareholder vote as may be
required by the 1940 Act or the Declaration of Trust. Also, a shareholder's
meeting must be called if so requested in writing by the holders of record of
10% or more of the outstanding shares of the Fund. In addition, the Trustees may
be removed by the action of the holders of record of two-thirds or more of the
outstanding shares.

    SHAREHOLDER LIABILITY. The Declaration of Trust provides that no Trustee,
officer, employee or agent of the Fund is liable to the Fund or to a
shareholder, nor is any Trustee, officer, employee or agent liable to any third
persons in connection with the affairs of the Fund, except as such liability may
arise from his or its own bad faith, willful misfeasance, gross negligence or
reckless disregard of his duties. It also provides that all third persons shall
look solely to the Fund's property for satisfaction of claims arising in
connection with the affairs of the Fund. With the exceptions stated, the
Declaration of Trust provides that a Trustee, officer, employee or agent is
entitled to be indemnified against all liability in connection with the affairs
of the Fund.

    As a Massachusetts business trust, the Fund is not required to issue share
certificates. The Fund shall continue without limitation of time subject to the
provisions in the Declaration of Trust concerning termination by action of the
shareholders.

    REPORTS TO SHAREHOLDERS. Shareholders of the Fund will receive annual and
semi-annual reports showing diversification of investments, securities owned and
other information regarding

the Fund's activities. The financial statements of the Fund are audited at least
once a year by the Fund's independent auditors.

    REGISTRATION STATEMENT. This Statement of Additional Information and the
Prospectus do not contain all of the information set forth in the Fund's
Registration Statement filed with the Securities and Exchange Commission. The
complete Registration Statement may be obtained from the Securities and Exchange
Commission upon payment of the fee prescribed by the rules and regulations of
the Commission.


                                   TAX STATUS

    The Fund has qualified and elected to be treated as a "regulated investment
company" under Subchapter M of the Internal Revenue Code of 1986, as amended
(the "Code"), and intends to continue to so qualify in the future. As such and
by complying with the applicable provisions of the Code regarding the sources of
its income, the timing of its distributions, and the diversification of its
assets, the Fund will not be subject to Federal income tax on taxable income
(including net short-term and long-term capital gains from the disposition of
portfolio securities or the right to when-issued securities prior to issuance,
or from the lapse, exercise, delivery under or closing out of options or futures
contracts, income from repurchase agreements and other taxable securities,
income attributable to accrued market discount, income from securities lending,
and a portion of the discount from certain stripped tax-exempt obligations or
their coupons) which is distributed to shareholders at least annually in
accordance with the timing requirements of the Code.

    The Fund will be subject to a 4% non-deductible Federal excise tax on
certain amounts not distributed (and not treated as having been distributed) on
a timely basis in accordance with annual minimum distribution requirements. The
Fund intends under normal circumstances to avoid liability for such tax by
satisfying such distribution requirements.

    Distributions from the Fund's current or accumulated earnings and profits
("E&P"), as computed for Federal income tax purposes, will be taxable as
described in the Fund's Prospectus whether taken in shares or in cash. Amounts
that are not allowable as a deduction in computing taxable income, including
expenses associated with earning tax-exempt interest income, do not reduce
current E&P for this purpose. Distributions, if any, in excess of E&P will
constitute a return of capital, which will first reduce an investor's tax basis
in Fund shares and thereafter (after such basis is reduced to zero) will
generally give rise to capital gains. Shareholders electing to receive
distributions in the form of additional shares will have a cost basis for
Federal income tax purposes in each share so received equal to the amount of
cash they would have received had they elected to receive the distributions in
cash, divided by the number of shares received.

    The Fund's distributions of tax-exempt interest ("exempt-interest
dividends") timely designated as such will be treated as tax-exempt interest
under the Code, provided that the Fund qualifies as a regulated investment
company and at least 50% of the value of its assets at the end of each quarter
of its taxable year is invested in tax-exempt obligations. Shareholders are
required to report their receipt of tax-exempt interest, including such
distributions, on their Federal income tax returns. The portion of the Fund's
distributions designated as exempt-interest dividends may differ from the actual
percentage that its tax-exempt income comprised of its total income during the
period of any particular shareholder's investment. The Fund will report to
shareholders the amount designated as exempt-interest dividends for each year.




                                      -27-
<PAGE>   135
    Interest income from certain types of tax-exempt bonds that are private
activity bonds in which the Fund may invest is treated as an item of tax
preference for purposes of the Federal alternative minimum tax. To the extent
that the Fund invests in these types of tax-exempt bonds, shareholders will be
required to treat as an item of tax preference for Federal alternative minimum
purposes that part of the Fund's exempt-interest dividends which is derived from
interest on these tax-exempt bonds. Exempt-interest dividends derived from
interest income from all tax-exempt bonds may be included in corporate "adjusted
current earnings" for purposes of computing the alternative minimum tax
liability, if any, of corporate shareholders of the Fund.

    The amount of the Fund's net short-term and long-term capital gains, if any,
in any given year will vary depending upon the Adviser's current investment
strategy and whether the Adviser believes it to be in the best interest of the
Fund to dispose of portfolio securities or enter into options or futures
transactions that will generate capital gains. At the time of an investor's
purchase of Fund shares, a portion of the purchase price is often attributable
to realized or unrealized appreciation in the Fund's portfolio or, less
frequently, to undistributed taxable income of the Fund. Consequently,
subsequent distributions from such appreciation or income may be taxable to such
investor even if the net asset value of the investor's shares is, as a result of
the distributions, reduced below the investor's cost for such shares, and the
distributions in reality represent a return of a portion of the purchase price.

    Upon a redemption of shares of the Fund (including by exercise of the
exchange privilege) a shareholder may realize a taxable gain or loss depending
upon his basis in his shares. Such gain or loss will be treated as capital gain
or loss if the shares are capital assets in the shareholder's hands and will be
long-term or short-term, depending upon the shareholder's tax holding period for
the shares. A sales charge paid in purchasing Class A shares of the Fund cannot
be taken into account for purposes of determining gain or loss on the redemption
or exchange of such shares within 90 days after their purchase to the extent
shares of the Fund or another John Hancock Fund are subsequently acquired
without payment of a sales charge pursuant to the reinvestment or exchange
privilege. Such disregarded load will result in an increase in the shareholder's
tax basis in the shares subsequently acquired. Also, any loss realized on a
redemption or exchange will be disallowed to the extent the shares disposed of
are replaced with identical or substantially identical securities within a
period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to an election to reinvest dividends in
additional shares. In such a case, the basis of the shares acquired will be
adjusted to reflect the disallowed loss. Any loss realized upon the redemption
of shares with a tax holding period of six months or less will be disallowed to
the extent of all exempt-interest dividends paid with respect to such shares
and, if not thus disallowed, will be treated as a long-term capital loss to the
extent of any amounts treated as distributions of long-term capital gain with
respect to such shares.

    Although its present intention is to distribute all net short-term and
long-term capital gains, if any, the Fund reserves the right to retain and
reinvest all or any portion of its "net capital gain," which is the excess, as
computed for Federal income tax purposes, of net long-term capital gain over net
short-term capital loss in any year. The Fund will not in any event distribute
net capital gain realized in any year to the extent that a capital loss is
carried forward from prior years against such gain. To the extent such excess
was retained and not exhausted by the carry forward of prior years' capital
losses, it would be subject to Federal income tax in the hands of the Fund. Each
shareholder would be treated for Federal income tax purposes as if the Fund had
distributed to him on the last day of its taxable year his pro rata share of
such excess, and he had paid his pro rata share of the taxes paid by the Fund
and reinvested the remainder in the Fund. Accordingly, each shareholder would
(a) include his pro rata share of such excess as long-term capital gain income
in his return for his taxable year in which the last day of the Fund's taxable
year falls, (b) be entitled either to a tax credit on his return for, or to a
refund of, his pro rata share of the taxes paid by the


                                      -28-
<PAGE>   136
Fund, and (c) be entitled to increase the adjusted tax basis for his shares in
the Fund by the difference between his pro rata share of such excess and his pro
rata share of such taxes.

    For Federal income tax purposes, the Fund is generally permitted to carry
forward a net capital loss in any year to offset its net capital gains, if any,
during the eight years following the year of the loss. To the extent subsequent
net capital gains are offset by such losses, they would not result in Federal
income tax liability to the Fund and, as noted above, would not be distributed
as such to shareholders. The Fund has $7,349,795 of capital loss carry forwards,
which expire in 2002, available to offset future net capital gains.

    Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Fund will not be deductible for Federal income tax purposes to the
extent it is deemed related to exempt-interest dividends paid by the Fund.
Pursuant to published guidelines, the Internal Revenue Service may deem
indebtedness to have been incurred for the purpose of purchasing or carrying
shares of the Fund even though the borrowed funds may not be directly traceable
to the purchase of shares.

    Dividends paid by the Fund to its corporate shareholders will not qualify
for the corporate dividends received deduction in their hands.

    If the Fund invests in zero coupon securities or, in general, any other
securities with original issue discount (or with market discount if the Fund
elects to include accrued market discount in income currently), the Fund must
accrue income on such investments prior to the receipt of the corresponding cash
payments. However, the Fund must distribute, at least annually, all or
substantially all of its net income, including such accrued income, to
shareholders to qualify as a regulated investment company under the Code and
avoid Federal income and excise taxes. Therefore, the Fund may have to dispose
of its portfolio securities under disadvantageous circumstances to generate
cash, or may have to leverage itself by borrowing the cash, to satisfy
distribution requirements.

    Limitations imposed by the Code on regulated investment companies like the
Fund may restrict the Fund's ability to enter into futures and options
transactions.

    Certain options and futures transactions undertaken by the Fund may cause
the Fund to recognize gains or losses from marking to market even though its
positions have not been sold or terminated and affect the character as long-term
or short-term and timing of some capital gains and losses realized by the Fund.
Also, certain of the Fund's losses on its transactions involving options or
futures contracts and/or offsetting portfolio positions may be deferred rather
than being taken into account currently in calculating the Fund's gains. These
transactions may therefore affect the amount, timing and character of the Fund's
distributions to shareholders. Certain of the applicable tax rules may be
modified if the Fund is eligible and chooses to make one or more of certain tax
elections that may be available. The Fund will take into account the special tax
rules (including consideration of available elections) applicable to options and
futures contracts in order to minimize any potential adverse tax consequences.

    The foregoing discussion relates solely to U.S. Federal income tax law as
applicable to U.S. persons (i.e., U.S. citizens or residents and U.S. domestic
corporations, partnerships, trusts or estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies, and financial
institutions. Dividends, capital gain distributions, and ownership of or gains
realized on the redemption (including an exchange) of Fund shares may also be
subject to state and local taxes. Shareholders should consult their own tax
advisers as to the Federal, state or local tax


                                      -29-
<PAGE>   137
consequences of ownership of shares of, and receipt of distributions from, the
Fund in their particular circumstances.

    Non-U.S. investors not engaged in a U.S. trade or business with which their
investment in the Fund is effectively connected will be subject to U.S. Federal
income tax treatment that is different from that described above. These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts treated as ordinary
dividends from the Fund and, unless an effective IRS Form W-8 or authorized
substitute is on file, to 31% backup withholding on certain other payments from
the Fund. Non- U.S. investors should consult their tax advisers regarding such
treatment and the application of foreign taxes to an investment in the Fund.

    The Fund is not subject to Massachusetts corporate excise or franchise
taxes. Provided that the Fund qualifies as a regulated investment company under
the Code, it will also not be required to pay any Massachusetts income tax.


                              BROKERAGE ALLOCATION

    Decisions concerning the purchase and sale of portfolio securities and the
allocation of brokerage commissions are made by the Investment Adviser pursuant
to recommendations made by its investment committee, which consists of officers
and directors of the Investment Adviser and affiliates and officers and Trustees
who are interested persons of the Fund. Orders for purchases and sales of
securities are placed in a manner which, in the opinion of the Investment
Adviser, will offer the best price and market for the execution of each such
transaction. Purchases from underwriters of portfolio securities may include a
commission or commissions paid by the issuer and transactions with dealers
serving as market makers reflect a "spread." Investments in debt securities are
generally traded on a net basis through dealers acting for their own account as
principals and not as brokers; no brokerage commissions are payable on such
transactions.

    The Fund's primary policy is to execute all purchases and sales of portfolio
instruments at the most favorable prices consistent with best execution,
considering all of the costs of the transaction including brokerage commissions.
This policy governs the selection of brokers and dealers and the market in which
a transaction is executed. Consistent with the foregoing primary policy, the
Rules of Fair Practice of the NASD and other policies that the Trustees may
determine, the Investment Adviser may consider sales of shares of the Fund as a
factor in the selection of broker-dealers to execute the Fund's portfolio
transactions.

    To the extent consistent with the foregoing, the Fund will be governed in
the selection of brokers and dealers, and the negotiation of brokerage
commission rates and dealer spreads, by the reliability and quality of the
services, including primarily the availability and value of research information
and to a lesser extent statistical assistance furnished to the Investment
Adviser of the Fund, and their value and expected contribution to the
performance of the Fund. It is not possible to place a dollar value on
information and services to be received from brokers and dealers, since it is
only supplementary to the research efforts of the Investment Adviser. The
receipt of research information is not expected to reduce significantly the
expenses of the Investment Adviser. The research information and statistical
assistance furnished by brokers and dealers may benefit the Life Company or
other advisory clients of the Investment Adviser, and conversely, brokerage
commissions and spreads paid by other advisory clients of the Investment Adviser
may result in research information and statistical assistance beneficial to the
Fund. The Fund will make no commitments to allocate portfolio transactions upon
any prescribed basis. While the Fund's officers will be primarily responsible
for the allocation of the Fund's brokerage business, their


                                      -30-
<PAGE>   138
policies and practices in this regard must be consistent with the foregoing and
will at all times be subject to review by the Trustees. For the fiscal years
ended December 31, 1994, 1993 and 1992, no negotiated brokerage commissions were
paid on portfolio transactions.

    As permitted by Section 28(e) of the Securities Exchange Act of 1934, the
Fund may pay to a broker which provides brokerage and research services to the
Fund an amount of disclosed commission in excess of the commission which another
broker would have charged for effecting that transaction. This practice is
subject to a good faith determination by the Trustees that the price is
reasonable in light of the services provided and to policies that the Trustees
may adopt from time to time. During the fiscal year ended December 31, 1994, the
Fund did not pay commissions as compensation to any brokers for research
services such as industry, economic and company reviews and evaluations of
securities.

    The Investment Adviser's indirect parent, the Life Company, is the indirect
sole shareholder of John Hancock Freedom Securities Corporation and its
subsidiaries, three of which, Tucker Anthony Incorporated ("Tucker Anthony")
John Hancock Distributors, Inc. ("John Hancock Distributors") and Sutro &
Company, Inc. ("Sutro"), are broker-dealers ("Affiliated Brokers"). Pursuant to
procedures determined by the Trustees and consistent with the above policy of
obtaining best net results, the Fund may execute portfolio transactions with or
through Tucker Anthony, Sutro or John Hancock Distributors. During the year
ended December 31, 1994, the Fund did not execute any portfolio transactions
with then affiliated brokers.

    Any of the Affiliated Brokers may act as broker for the Fund on exchange
transactions, subject, however, to the general policy of the Fund set forth
above and the procedures adopted by the Trustees pursuant to the 1940 Act.
Commissions paid to an Affiliated Broker must be at least as favorable as those
which the Trustees believe to be contemporaneously charged by other brokers in
connection with comparable transactions involving similar securities being
purchased or sold. A transaction would not be placed with an Affiliated Broker
if the Fund would have to pay a commission rate less favorable than the
Affiliated Broker's contemporaneous charges for comparable transactions for its
other most favored, but unaffiliated, customers, except for accounts for which
the Affiliated Broker acts as a clearing broker for another brokerage firm, and
any customers of the Affiliated Broker not comparable to the Fund as determined
by a majority of the Trustees who are not interested persons (as defined in the
1940 Act) of the Fund, the Investment Adviser or the Affiliated Brokers. Because
the Investment Adviser, which is affiliated with the Affiliated Brokers, has, as
an investment adviser to the Fund, the obligation to provide investment
management services, which includes elements of research and related investment
skills, such research and related skills will not be used by the Affiliated
Brokers as a basis for negotiating commissions at a rate higher than that
determined in accordance with the above criteria. The Fund will not effect
principal transactions with Affiliated Brokers.

    The Fund's portfolio turnover rates for the fiscal years ended December 31,
1993 and 1994 were 116% and 107%, respectively.


                            TRANSFER AGENT SERVICES

    John Hancock Investor Services Corporation, P.O. Box 9116, Boston, MA
02205-9116, a wholly owned indirect subsidiary of the Life Company, is the
transfer and dividend paying agent for the Fund. The Fund pays Investor Services
a monthly transfer agent fee of $19 per account for the Class A Shares and
$22.50 per account for the Class B Shares, plus out-of-pocket expenses.

                              INDEPENDENT AUDITORS

    Ernst & Young LLP, 200 Clarendon Street, Boston, Massachusetts 02116, has
been selected as the independent auditors of the Fund. The financial statements
of the Fund included in the Prospectus and this Statement of Additional
Information have been audited by Ernst & Young LLP for the periods indicated in
their report thereon appearing elsewhere herein, and are included in reliance
upon such report given upon the authority of such firm as experts in accounting
and auditing.


                              CUSTODY OF PORTFOLIO

    Investor Bank and Trust ("IBT") 24 Federal Street, Boston, Massachusetts,
serves as custodian of the cash and investment securities of the Fund. IBT is
also responsible for, among other things, receipt and delivery of the Fund's
investment securities in accordance with procedures and conditions specified in
the custody agreement.


                           CALCULATION OF PERFORMANCE

    For the 30-day period ended December 31, 1994, the annualized yields of the
Fund's Class A Shares and Class B Shares were 6.13% and 5.68%, respectively.
    As of December 31, 1994, the average annual total returns of the Class A
Shares of the Fund for the one year period and since inception on January 1,
1990 were -13.61% and 6.11%, respectively (-13.71% and 5.74%, respectively,
without taking into account the expense limitation arrangements). As of December
31, 1994, the average annual returns for the Fund's Class B Shares for the one
year period and since inception on December 31, 1991 were -15.05% and 3.31%,
respectively (-15.05% and 3.11%, respectively, without taking into account the
expense limitation arrangements).
    The Fund's yield is computed by dividing net investment income per share
determined for a 30-day period by the maximum offering price per share (which
includes the full sales charge) on the last day of the period, according to the
following standard formula:

Yield  =  2 [ (a-b + 1 )6  -1]
               ---
               cd

Where:

    a= dividends and interest earned during the period.

    b= net expenses accrued during the period.

    c= the average daily number of fund shares outstanding during the period
       that would be entitled to receive dividends.

    d= the maximum offering price per share on the last day of the period (NAV
       where applicable).

    The Fund may advertise a tax-equivalent yield, which is computed by dividing
that portion of the yield of the Fund which is tax-exempt by one minus a stated
income tax rate and adding the product to that portion, if any, of the yield of
the Fund that is not tax-exempt. The tax equivalent yields for the Fund's Class
A and Class B Shares at the maximum 36% tax rate for the 30-day period ended
December 31, 1994 were 9.70% and 9.40%, respectively.



                                      -32-
<PAGE>   140
    The Fund's total return is computed by finding the average annual compounded
rate of return over the 1-year, 5-year, and 10-year periods that would equate
the initial amount invested to the ending redeemable value according to the
following formula:

                                 P(1 + T)n = ERV

Where:

    P=   a hypothetical initial investment of $1,000.

    T=   average annual total return

    n=   number of years

    ERV= ending redeemable value of a hypothetical $1,000 investment made at the
         beginning of the 1-year and life-of-fund periods.

    In the case of Class A Shares or Class B Shares, this calculation assumes
the maximum sales charge is included in the initial investment or the CDSC is
applied at the end of the period. This calculation also assumes that all
dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period. The "distribution rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.

    In addition to average annual total returns, the Fund may quote unaveraged
or cumulative total returns reflecting the simple change in value of an
investment over a stated period. Cumulative total returns may be quoted as a
percentage or as a dollar amount, and may be calculated for a single investment,
a series of investments, and/or a series of redemptions, over any time period.
Total returns may be quoted with or without taking the Fund's maximum sales
charge on Class A Shares or the CDSC on Class B Shares into account. Excluding
the Fund's sales charge on Class A Shares and the CDSC on Class B Shares from a
total return calculation produces a higher total return figure.

    From time to time, in reports and promotional literature, the Fund's yield
and total return will be compared to indices of mutual funds and bank deposit
vehicles such as Lipper Analytical Services, Inc.'s "Lipper -- Fixed Income Fund
Performance Analysis," a monthly publication which tracks net assets, total
return, and yield on approximately 1,700 fixed income mutual funds in the United
States. Ibottson and Associates, CDA Weisenberger and F.C. Towers are also used
for comparison purposes, as well a the Russell and Wilshire Indices.
    Performance rankings and ratings reported periodically in national financial
publications such as MONEY Magazine, FORBES, BUSINESS WEEK, THE WALL STREET
JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S and BARRON'S, etc. will also be
utilized. The Fund's promotional and sales literature may make reference to the
Fund's "beta." Beta is a reflection of the market-related risk of the Fund by
showing how responsive the Fund is to the market.
    The performance of the Fund is not fixed or guaranteed. Performance
quotations should not be considered to be representations of performance of the
Fund for any period in the future. The performance of the Fund is a function of
many factors including its earnings, expenses and number of outstanding shares.
Fluctuating market conditions; purchases, sales and maturities of portfolio
securities; sales and redemptions of shares of beneficial interest; and changes
in operating expenses are all examples of items that can increase or decrease
the Fund's performance.

                      CORPORATE AND TAX-EXEMPT BOND RATINGS


MOODY'S INVESTORS SERVICE, INC. ("MOODY'S)

    ASS, AA, A AND BAA - Tax-exempt bonds rated Aaa are judged to be of the
"best quality." The rating of Aa is assigned to bonds that are of "high quality
by all standards," but long-term risks appear somewhat larger than Aaa rated
bonds. The Aaa and Aa rated bonds are generally known as "high grade bonds." The
foregoing ratings for tax-exempt bonds are rated conditionally. Bonds for which
the security depends upon the completion of some act or upon the fulfillment of
some condition are rated conditionally. These are bonds secured by (a) earnings
of projects under construction, (b) earnings of projects unseasoned in operation
experience, (c) rentals that begin when facilities are completed, or (d)
payments to which some other limiting condition attaches. Such parenthetical
ratings denotes the probable credit stature upon completion of construction or
elimination of the basis of the condition. Bonds rated A are considered as upper
medium grade obligations. Principal and interest are considered adequate, but
elements may be present which suggest a susceptibility to impairment sometime in
the future. Bonds rated Baa are considered a medium grade obligations; i.e.,
they are neither highly protected or poorly secured. Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact, have speculative characteristics as well.

STANDARD & POOR'S CORPORATION ("S&P")

    AAA, AA, A AND BBB - Bonds rated AAA bear the highest rating assigned to
debt obligations and indicates an extremely strong capacity to pay principal and
interest. Bonds rated AA are considered "high grade," are only slightly less
marked than those of AAA ratings and have the second strongest capacity for
payment of debt service. Bonds rated A have a strong capacity to pay principal
and interest, although they are somewhat susceptible to the adverse effects or
changes in circumstances and economic conditions. The foregoing ratings are
sometimes followed by a "p" indicating that the rating is provisional. A
provisional rating assumes the successful completion of the project financed by
the bonds being rated and indicates that payment of debt service requirements is
largely or entirely dependent upon the successful and timely completion of the
project. Although a provisional rating addresses credit quality subsequent of
completion of the project, it makes no comment on the likelihood of, or the risk
of default upon failure of, such completion. Bonds rated BBB are regarded as
having an adequate capacity to repay principal and pay interest. Whereas they
normally exhibit protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to repay principal
and pay interest for bonds in this category than for bonds in the A category.

FITCH INVESTORS SERVICE ("FITCH")

    AAA, AA, A, BBB - Bonds rated AAA are considered to be investment grade and
of the highest quality. The obligor has an extraordinary ability to pay interest
and repay principal, which is unlikely to be affected by reasonably foreseeable
events. Bonds rated AA are considered to be investment grade and of high
quality. The obligor's ability to pay interest and repay principal, while very
strong, is somewhat less than for AAA rated securities or more subject to
possible change over the term of the issue. Bonds rated A are considered to be
investment grade and of


                                       A-1
<PAGE>   145
good quality. The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings. Bonds
rated BBB are considered to be investment grade and of satisfactory quality. The
obligor's ability to pay interest and repay principal is considered to be
adequate. Adverse changes in economic conditions and circumstances, however, are
more likely to weaken this ability than bonds with higher ratings.

                            TAX-EXEMPT NOTE RATINGS

    MOODY'S - MIG-1 AND MIG-2. Notes rated MIG-1 are judged to be of the best
quality, enjoying strong protection from established cash flow or funds for
their services or from established and broad-based access to the market for
refinancing or both. Notes rated MIG-2 are judged to be of high quality with
ample margins of protection, though not as large as MIG-1.

    S&P - SP-1 AND SP-2. SP-1 denotes a very strong or strong capacity to pay
principal and interest. Issues determined to possess overwhelming safety
characteristics are given a plus (+) designation (SP-1+). SP-2 denotes a
satisfactory capacity to pay principal interest.

    FITCH - FIN-1 AND FIN-2. Notes assigned FIN-1 are regarded as having the
strongest degree of assurance for timely payment. A plus symbol may be used to
indicate relative standing. Notes assigned FIN-2 reflect a degree of assurance
for timely payment only slightly less in degree than the highest category.

               CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

    MOODY'S - Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Prime-1, indicates highest quality repayment capacity of
rated issue and Prime-2 indicates higher quality.

    S&P - Commercial Paper ratings are a current assessment of the likelihood of
timely payment of debts having an original maturity of no more than 365 days.
Issues rated A have the greatest capacity for a timely payment and the
designation 1, 2 and 3 indicates the relative degree of safety. Issues rated
"A-1+" are those with an "overwhelming degree of credit protection."

    FITCH - Commercial Paper ratings reflect current appraisal of the degree of
assurance of timely payment. F-1 issues are regarded as having the strongest
degree of assurance for timely payment. (+) is used to designate the relative
position of an issuer within the rating category. F-2 issues reflect an
assurance of timely payment only slightly less in degree than the strongest
issues. The symbol (LOC) may follow either category and indicates that a letter
of credit issued by a commercial bank is attached to the commercial paper note.

    OTHER CONSIDERATIONS - The ratings of S&P, Moody's, and Fitch represent
their respective opinions of the quality of the municipal securities they
undertake to rate. It should be emphasized, however, that ratings are general
and are not absolute standards of quality. Consequently, municipal securities
with the same maturity, coupon and ratings may have different yields and
municipal securities of the same maturity and coupon with different ratings may
have the same yield.

                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

[A 1 1/4" x 1" photo of Edward J. Boudreau Jr., Chairman and Chief Executive
Officer, flush right, next to second paragraph.]

The stock market's record-breaking, whirlwind performance in 1995 will be a
tough act to follow in 1996. In fact, we've already seen greater market
volatility this year, particularly among last year's leaders -- technology
stocks. That's to be expected after a year that saw market indexes soar,
including the Standard & Poor's 500-Stock Index's 37% advance. While many of the
same economic conditions that fostered the stellar 1995 market are still in
place -- slow economic growth, muted inflation and decent corporate earnings --
it would be unrealistic to expect the market to stage a repeat in 1996. The old
saying "trees don't grow to the sky" comes to mind. Shareholders would do well
to temper expectations of investment returns and perhaps revisit their
investment allocations with their financial advisor to determine if rebalancing
their portfolio makes sense.

       No matter how you scale back your market expectations, you should always
be able to count on consistent customer service performance. At John Hancock
Funds, we never stop working to find ways to sustain and improve the quality of
information and the level of assistance we provide you. Our commitment to this
task is no less than John Hancock's loyalty was to his fledgling country when he
is said to have uttered, "if it does the public good, burn Boston." We won't go
that far, of course, but we share our namesake's dedication to putting the
public before all else.

       In our case, that public is you, our shareholders. We take very seriously
the role you have entrusted to us, that of helping you achieve your financial
goals. Part of that will always involve good customer service. So please do not
hesitate to call your Customer Service Representative at 1-800-225-5291 if you
have any questions or need information. We take pride in helping you with the
same spirit that John Hancock displayed at the dawning of America.

Sincerely,

/s/ Edward J. Boudreau, Jr.

              "SOFT LANDING" HELPED BOOST MUNICIPAL PRICES IN 1995

Slowing economic growth and easing inflationary pressures provided the backdrop
for an unexpectedly strong bond market rally in 1995. The year got off to an
impressive start as more investors came to accept that the Federal Reserve Board
could actually engineer a "soft landing" -- in which economic growth is slow but
steady and inflation remains low. The first quarter was particularly strong for
municipal bonds, which outpaced Treasury, mortgage and corporate bonds alike.

[A 2 1/4" x 3" photo of Thomas C. Goggins at bottom right. Caption reads:
"Thomas C. Goggins".]

       However, various tax-reform proposals grabbed the headlines in the second
quarter and stymied the rise of municipals. At issue was the notion that some
proposals, particularly the flat-tax proposal, could eliminate any need for
investors to own tax-exempt securities. But by the fall, municipals started to
regain some steam. Two interest-rate cuts in the last two quarters of the year,
coupled with rising demand for municipals from some institutional investors,
ignited another round of strength. By the end of 1995, municipals had turned in
their best performance since 1986.

A LOOK AT PERFORMANCE

John Hancock Tax-Free Bond Fund performed well, not only in absolute terms, but
also compared to its competitors. For the year ended December 31, 1995, the
Fund's Class A and Class B shares posted total returns of 20.20% and 19.41%,
respectively, at net asset value. Those returns outpaced the average general
municipal bond fund's return of 16.84% for the same period, according to Lipper
Analytical Services.(1)

       There were several factors contributing to the Fund's better-than-average
performance. First was duration, which measures how sensitive

                                   [CAPTION]
              "BY THE END OF 1995, MUNICIPALS HAD TURNED IN THEIR
                         BEST PERFORMANCE SINCE 1986."

lists five sectors: 1) Transportation 21%; 2) Electric Utilities 18%; 3) Health
18%; 4) General Obligation Bonds 11%; 5) Pollution Control 10%. Footnote below

the Fund's share price is to changes in interest rates. In the first quarter of
the year, the Fund's duration was relatively long, which benefited its
performance when interest rates were falling. In the second quarter we reduced
our duration by replacing some longer-term bonds with shorter-term bonds. We did
that because there wasn't much difference in yield between short- and long-term
bonds. In other words, we did not give up a great amount of yield to own the
less volatile, shorter-term bonds. That strategy also paid off because the
second quarter was a particularly volatile period for municipal bonds. By the
fall, however, we felt that interest rates could resume their decline, so we
made the Fund more interest-rate sensitive by lengthening our duration again.
Having a longer duration during the second half of the year also helped our
performance.

       Our continued focus on non-callable bonds was also an advantage for the
Fund. Non-callable bonds are so-called because they can't be redeemed by their
issuer before their scheduled maturity dates. They tended to benefit more fully
from the bond market rally than callable bonds. A bond with a call will trade
under the assumption that the issuer will call the bond -- or pay it off -- on
the call provision date, which is the first date it can be redeemed by its
issuer. As the call date approaches, callable bonds are less likely to
participate fully in a rally. Non-callable bonds also offer another advantage:
they provide a predictable and steady stream of income. If interest rates
decline further, our non-callable bonds can't be redeemed early, so we won't be
forced to put the proceeds from calls back to work in the market at lower
interest rates.

       Finally, we focused on buying discount bonds, which sell below par (face)
value. During periods when interest rates are declining, discount bonds tend to
appreciate more than par bonds, and more than premium bonds, which trade above
par value.

FOCUS ON SECTORS

Transportation bonds made up the Fund's largest sector concentration at about
21% of net assets at the end of 1995. During the period we added several
industrial development bonds in the airline sector, which our team of analysts
identified as having good prospects for appreciation. Dallas/Fort Worth issued
bonds to construct additional gates for American Airlines at the airport.
Indianapolis issued bonds for a United Airlines maintenance facility. These

were two of the Fund's largest holdings and best performers for the year.

       Housing bonds, which posted weak gains during 1995, were the municipal
market's laggards. These bonds were held back by the perception that mortgages
underlying these housing bonds would be refinanced as interest rates fall.
However, we've maintained a core holding in high-quality, high-yielding housing
bonds that we think are less vulnerable to early payment.

       The Fund's Trustees recently voted to give the Fund the flexibility to
invest as much as one-third of its assets in high-yielding bonds that carry
below investment-grade ratings. We plan to be selective in adding these bonds,
buying them only when we think that they offer enough reward to justify the risk
taken.

OUTLOOK

Political haggling over various tax-reform proposals could continue to draw
headlines in 1996. If that is the case, the municipal bond market could
experience further volatility in the months to come. We think it's unlikely that
any significant tax reform will be enacted within the next two years. And we're
not convinced that the flat tax is viable. So in our view, the market has
overreacted. We believe that the tax-reform scare has actually created an
opportunity. At the end of 1995, municipals were priced attractively compared to
Treasuries. In fact, there was only one other time in recent history that
municipals were this cheap relative to Treasuries. In our experience, it is in
times like these that municipals offer good value for investors seeking
after-tax income.

       It may be difficult for municipals to achieve the same exceptional gains
they made in 1995. However, there are several reasons why we're optimistic about
1996. We believe economic growth will continue to slow, inflation will remain
subdued and, as a result, interest rates could continue to fall. Since bond
prices generally move in the opposite direction of interest rates, that could be
good news for bonds. What's more, the supply of new municipals issued should
remain relatively weak. And if demand stays constant or improves, that too could
be a positive.

                              A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Tax-Free Bond Fund. Total return is a
performance measure that equals the sum of all dividends and capital gains,
assuming reinvestment of these distributions and the change in the price of the
Fund's average net assets. Performance figures included the maximum applicable
sales charge of 4.50% for Class A shares. The effect of the maximum contingent
deferred sales charge for Class B shares (maximum 5% and declining to 0% over
six years) is included in Class B performance. Remember that all figures
represent past performance and are no guarantee of how the Fund will perform in
the future. Also, keep in mind that the total return and share price of the
Fund's investments will fluctuate. As a result, your Fund's shares may be worth
more or less than their original cost, depending on when you sell them.

Note: A portion of the Fund's income may be subject to taxes. Some investors may
be subject to the Alternative Minimum Tax. Capital gains are taxable.

(3) The Adviser has agreed to limit the Fund's expenses, including the
    management fee (but not including the 12b-1 fee), to 0.70% of the Fund's
    average daily net assets. Without the limitation of expenses, the average
    annualized total returns for the one-year and five-year periods and since
    inception for Class A shares would have been 14.67%, 8.62%, and 8.06%,
    respectively. The average annualized total returns for the one-year period
    and since inception for Class B shares would have been 14.30% and 7.07%,
    respectively.

The charts on the right show how much a $10,000 investment in the John Hancock
Tax-Free Bond Fund would be worth on December 31, 1995, assuming you have been
invested since the day each class of shares started and reinvested all
distributions. For comparison, we've shown the same $10,000 investment in the
Lehman Brothers Municipal Bond Index -- an unmanaged index that includes
approximately 15,000 bonds and is commonly used as a measure of bond
performance.

                     John Hancock Funds - Tax-Free Bond Fund


NOTE A --
ACCOUNTING POLICIES

John Hancock Tax-Free Bond Fund (the "Fund") is a diversified open-end
investment management company registered under the Investment Company Act of
1940.

   The investment objective of the Fund is to obtain as high a level of interest
income exempt from federal income taxes as is consistent with preservation of
capital by investing primarily in municipal bonds, notes and commercial paper,
the interest on which is exempt from federal income taxes.

   The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, dividends and liquidation, except that certain expenses,
subject to the approval of the Trustees, may be applied differently to each
class of shares in accordance with current regulations of the Securities and
Exchange Commission. Shareholders of a class which bears distribution/service
expenses under the terms of a distribution plan, have exclusive voting rights
regarding such distribution plan. Class A shares are subject to an initial sales
charge of up to 4.50% and a 12b-1 distribution plan. Prior to May 15, 1995, the
maximum sales charge was 4.75%. Class B shares are subject to a contingent
deferred sales charge and a separate 12b-1 distribution plan. Significant
accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or, at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly-owned subsidiary of The Berkeley Financial Group,
may participate in a joint repurchase agreement. Aggregate cash balances are
invested in one or more repurchase agreements, whose underlying securities are
obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $12,505,428 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. If such carryforwards are used by the Fund,
no capital gain distributions will be made. The carryforwards expire as follows:
December 31, 2002 -- $7,349,795, December 31, 2003 -- $5,155,633. Expired
capital loss carryforwards are reclassified to capital paid-in, in the year of
expiration.

DIVIDENDS, DISTRIBUTIONS, AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

   The Fund records all distributions to shareholders from net investment income
and realized gains on the ex-dividend date. Such distributions are determined in
conformity with income tax regulations, which may differ from generally accepted
accounting principles. Dividends paid by the Fund with respect to each class of
shares will be calculated in the same manner, at the same time and will be in
the same amount, except for the effect of expenses that may be applied
differently to each class as explained previously.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution/service fees, if any, are calculated daily at the class level based
on the appropriate

net assets of each class and the specific expense rate(s) applicable of each
class.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. At the time the Fund enters into a financial futures
contract, it is required to deposit with its custodian a specified amount of
cash or U.S. government securities, known as "initial margin", equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract is valued at the official settlement price of the
board of trade or U.S. commodities exchange. Subsequent payments, known as
"variation margin", to and from the broker are made on a daily basis as the
market price of the financial futures contract fluctuates. Daily variation
margin adjustments, arising from this "mark to market", are recorded by the Fund
as unrealized gains or losses.

   When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening, or realizing the benefits of closing
out, futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

   For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

   At December 31, 1995, open positions in financial futures contracts were as
follows:

   At December 31, 1995, the Fund has deposited in a segregated account $895,000
par value of Clark County, Nevada Industrial Development Revenue Bond, 6.50%,
12/01/33 to cover margin requirements on open financial futures contracts.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

NOTE B --
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program at an annual
rate of 0.55% of the Fund's average daily net asset value.

   In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares, the fee payable to the
Adviser will be reduced to the extent of such excess, and the Adviser will make
additional arrangements necessary to eliminate any remaining excess expenses.
The current limits are 2.5% of the first $30,000,000 of the Fund's average daily
net asset value, 2.0% of the next $70,000,000, and 1.5% of the remaining average
daily net asset value.

   The Adviser has agreed to limit Fund expenses, including the management fee
(but not including the 12b-1 fee), to 0.70% of the Fund's average daily net
assets. Accordingly, the reduction in the Adviser's fee amounted to $208,207 for
the period ended December 31, 1995. This reduction may be discontinued at any
time. Furthermore, $24,419 of custodian fees have been reduced by balance
credits applied during the period ended December 31, 1995.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly-owned subsidiary of the Adviser. For the period ended December
31, 1995, JH Funds received net sales charges

                     John Hancock Funds - Tax-Free Bond Fund


on sales of Class A shares of the Fund in the amount of $158,248. Out of this
amount, $14,871 was retained and used for printing prospectuses, advertising,
sales literature and other purposes, $68,756 was paid as sales commissions and
service fees to unrelated broker-dealers and $74,621 was paid as sales
commissions and service fees to sales personnel of John Hancock Distributors,
Inc. ("Distributors"), Tucker Anthony, Incorporated ("Tucker Anthony") and Sutro
& Co., Inc. ("Sutro"), all of which are broker-dealers. The Adviser's indirect
parent, John Hancock Mutual Life Insurance Company, is the indirect sole
shareholder of Distributors and John Hancock Freedom Securities Corporation and
its subsidiaries, which include Tucker Anthony and Sutro.

   Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from CDSC are paid to JH Funds and are used in whole or in part to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended December 31,
1995, contingent deferred sales charges received by JH Funds amounted to
$222,466.

   In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A and Class B shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses at an annual rate not to exceed
0.15% of Class A average daily net assets and 0.90% of Class B average daily net
assets to reimburse JH Funds for its distribution and service costs. Up to a
maximum of 0.15% of these payments may be service fees as defined by the amended
Rules of Fair Practice of the National Association of Securities Dealers. Under
the amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

   The Board of Trustees approved a shareholder servicing agreement between the
Fund and John Hancock Investor Services Corporation ("Investor Services"), a
wholly-owned subsidiary of The Berkeley Financial Group, for the period between
December 22, 1994 and May 12, 1995, inclusive under which Investor Services
processed telephone transactions on behalf of the Fund. For the period May 15,
1995 through September 30, 1995, the Fund entered into a full service transfer
agent agreement with Investor Services whereby Class A and Class B shares paid
transfer agent fees based on the number of shareholder accounts and certain
out-of-pocket expenses. Prior to May 15, 1995 The Shareholder Services Group was
the transfer agent. Effective October 1, 1995 transfer agent expense is a fund
expense.

   Messrs. Edward J. Boudreau, Jr. and Richard S. Scipione are directors and/or
officers of the Adviser, and/or its affiliates as well as Trustees of the Fund.
The compensation of unaffiliated Trustees is borne by the Fund.

   Effective with the fees paid for 1995, the unaffiliated Trustees may elect to
defer for tax purposes their receipt of this compensation under the John Hancock
Group of Funds Deferred Compensation Plan. The Fund makes investments into other
John Hancock funds, as applicable, to cover its liability with regard to the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability is marked to market on a periodic basis and income earned
by the investment is recorded on the Fund's books.

   The Fund has an independent advisory board composed of certain members of the
former Transamerica Board of Trustees who provide advice to the current Trustees
in order to facilitate a smooth management transition. The Fund pays the
advisory board and its counsel a fee.

NOTE C --
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term securities, during the period
ended December 31, 1995, aggregated $211,980,373 and $211,965,175, respectively.
There were no purchases or sales of long-term obligations of the U.S. government
and its agencies during the period ended December 31, 1995.

   The cost of investments owned at December 31, 1995 for Federal income tax
purposes was $190,204,887. Gross unrealized appreciation and depreciation of
investments aggregated $15,264,006 and $26,410, respectively, resulting in net
unrealized appreciation of $15,237,596.

NOTE D --
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended December 31, 1995, the Fund has reclassified $80,005 from
undistributed net investment income and $63,964 from accumulated net realized
loss on investments and financial futures contracts to capital paid-in. This
represents the cumulative amounts necessary to report these balances on a tax
basis, excluding certain temporary differences, as of December 31, 1995.
Additional adjustments may be needed in subsequent reporting periods. These
reclassifications, which have no impact on the net asset value of the Fund, are
primarily attributable to certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles.

PLAN OF REORGANIZATION

On November 28, 1995, the Board of Trustees of the Fund approved a plan of
reorganization between the Fund and the John Hancock Tax-Exempt Income Fund
("Income Fund") providing for the transfer of substantially all of the assets
and liabilities of the Income Fund to the Fund in exchange solely for Class A
and Class B shares of the Fund to be distributed to Income Fund's Class A and
Class B shareholders, respectively.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT AUDITORS

To the Board of Trustees and Shareholders of
John Hancock Tax-Free Bond Fund

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the John Hancock Tax-Free Bond (the "Fund"), as
of December 31, 1995, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1995, by correspondence with the custodian and brokers, or other
appropriate auditing procedures when replies from brokers were not received. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
John Hancock Tax-Free Bond Fund at December 31, 1995, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the indicated periods, in conformity with generally accepted accounting
principles.

FINANCIAL STATEMENTS
</TABLE>

ORGANIZATION OF THE FUND

     John Hancock Tax-Exempt Income Fund (the "Fund") is a diversified,
open-end management investment company organized in 1976 by John Hancock
Advisers, Inc. (the "Adviser") as a Massachusetts business trust under the laws
of The Commonwealth of Massachusetts. The Adviser is an indirect wholly-owned
subsidiary of John Hancock Mutual Life Insurance Company (the "Life Insurance
Company"), a Massachusetts life insurance company chartered in 1862, with
national headquarters at John Hancock Place, Boston, Massachusetts. Prior to May
1, 1991, the Fund was known as "John Hancock Tax-Exempt Income Trust."


INVESTMENT OBJECTIVE AND POLICIES

        The investment objective of the Fund is to provide its shareholders
with as high a level of dividend income exempt from Federal income tax as is
consistent with preservation of capital and the Fund's requirements for
liquidity. The Fund will seek to achieve its objective by investing in a
diversified portfolio of municipal bonds and other securities (including
certain industrial development or private activity bonds), the interest on
which is, at 
<PAGE>   172

the time of issue, excludable from gross income for Federal income tax purposes
in the opinion of bond counsel to the issuer (all of which are commonly known as
"Tax-Exempt Bonds"). The type of securities the Fund invests in are described in
the Prospectus.

     Subsequent to its purchase by the Fund, an issue of Tax-Exempt Bonds
may cease to be rated or its rating may be reduced below the minimum required
for purchase by the Fund. Neither event will require the elimination of the
issue from the Fund's portfolio, but the change may affect the Fund's ability to
buy additional Tax-Exempt Bonds within categories restricted by the limitations
referred to in the Prospectus and will be analyzed by the Fund in determining
whether it should continue to hold the issue. If at any time the nature of the
ratings utilized by Moody's Investors Service Inc. ("Moody's"), Standard &
Poor's Ratings Group ("Standard and Poor's") or Fitch Investors Services, Inc.
("Fitch") should no longer be comparable to the description of ratings included
in Appendix A to the Prospectus, the Fund will attempt to use ratings comparable
to those described in Appendix A as standards for making investments in
Tax-Exempt Bonds in accordance with its investment objective.

     Securities will be purchased and sold principally in response to the
Fund's current evaluation of an issuer's ability to meet its debt obligations in
the future and the Fund's current assessment of future changes in the levels of
interest rates on Tax-Exempt Bonds of varying maturities. In some instances, the
sale of a portfolio security could result in a capital loss to the Fund.

When-Issued Securities. Newly issued Tax-Exempt Bonds may be purchased by the
Fund on a "when-issued" basis, which means that the bonds are not delivered
until a future date that may be as many as 45 days after the Fund has agreed to
purchase the Bonds. Until delivery, the Fund does not pay for Tax-Exempt Bonds
purchased on a "when-issued" basis and does not start earning interest on them,
but the Fund is committed to pay for the Bonds on a fixed date at a fixed price.
During the period before the delivery of the Bonds, the Fund could have
unrealized gains or losses if the Bonds' market value increased or decreased
relative to the agreed-upon purchase price. The Fund does not intend to make
when-issued commitments for speculative purposes but only to accomplish the
investment objective of the Fund as set forth above. On the date the Fund enters
into an agreement to purchase Tax-Exempt Bonds on a when-issued basis, the Fund
segregates in a separate account cash or liquid high grade debt securities equal
in value to the when-issued commitment. These assets will be valued daily at
market, and additional cash or securities will be segregated in a separate
account to the extent that the total value of the assets in the account declines
below the amount of the when-issued commitment.

     In general, Tax-Exempt Bonds are debt obligations issued by states,
territories and possessions of the United States, the District of Columbia and
their political subdivisions, agencies and instrumentalities.

     Tax-Exempt Bonds are issued to obtain funds for various public
purposes, including the construction of bridges, highways, housing, hospitals,
mass transportation, schools, streets, and water and sewer works. Other public
purposes for which Tax-Exempt Bonds may be issued include the refunding of
outstanding obligations, obtaining funds for general operating expenses,
obtaining funds to loan to other public institutions and facilities and in
anticipation of the receipt of revenue or the issuance of other obligations. In
addition, the term Tax-Exempt Bonds includes certain types of private activity
bonds, including industrial development bonds, issued by public authorities to
obtain funds to provide privately-operated housing facilities, sports
facilities, convention or trade show facilities, airport, mass transit, port or
parking facilities, air or water pollution control facilities and certain
facilities for water supply, gas, electricity or sewage or solid waste disposal.
Other types of industrial development bonds, the proceeds of which are used for
the acquisition, construction, reconstruction, or improvement of or to provide
equipment for privately-operated industrial or commercial facilities, may
qualify as Tax-Exempt Bonds, although current Federal tax laws place substantial
limitations on the size of such issues. Federal tax legislation enacted in the
1980's placed substantial new restrictions on the issuance of the bonds
described above and in some cases eliminated the ability of state or local
governments to issue Tax-Exempt Bonds for some of the above purposes. Such
restrictions do not affect the Federal income tax treatment of Tax-Exempt Bonds
in which the Fund may invest which were issued prior to the effective dates of
the provisions imposing such restrictions. The effect of these restrictions may
be to reduce the volume of newly issued Tax-Exempt Bonds.

<PAGE>   173

     Obligations of issuers of Tax-Exempt Bonds are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the Federal Bankruptcy Act, and laws, if any,
which may be enacted by Congress or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
enforcement of such obligations. There is also the possibility that as a result
of litigation or other conditions the power or ability of any one or more
issuers to pay when due, principal of and interest on, their Tax-Exempt Bonds,
may be affected.

     Tax-Exempt Bonds may be either "general obligation" bonds or "revenue"
bonds. General obligation bonds are secured by the issuer's pledge of its faith,
credit and taxing power for the payment of principal and interest. The taxes or
special assessments that can be levied for the payment of debt service may be
limited or unlimited as to rate or amount. Revenue bonds are payable only from
the revenues derived from a particular facility or class of facilities or, in
some cases, from the proceeds of a special excise or other specific revenue
source. Private Activity bonds which are Tax-Exempt Bonds are in most cases
revenue bonds and do not generally constitute the pledge of the credit or taxing
power of the issuer of such bonds. The credit quality of such Tax-Exempt Bonds
is usually directly related to the credit standing of the user of the
facilities. Private activity bonds may be backed by bank letters of credit or by
guarantees of banks or other institutions, which may be called upon by the
holders of the underlying obligations in the event of the issuer's default.

     There are three major classes of short-term Tax-Exempt debt
instruments. The names used to designate these loans are "bond anticipation
notes," "tax anticipation notes," and "revenue anticipation notes". Bond
anticipation notes are issued as interim debt instruments in anticipation of
funding through longer term bond financing. Tax anticipation notes are issued
against and are repayable from tax collections. Revenue anticipation notes are
issued against and repayable from the receipt of a specific future revenue or
are general obligations of the issuer.

     The yields on Tax-Exempt Bonds are dependent on a variety of factors,
including general money market conditions, supply and demand, general conditions
of the Tax-Exempt Bond market, the size of a particular offering, the maturity
of the obligation and the rating of the issuer. The ratings of Moody's, Standard
and Poor's and Fitch represent their opinions as to the quality of the
Tax-Exempt Bonds which they undertake to rate. It should be emphasized, however,
that such ratings are general and are not absolute standards of quality.
Consequently, Tax-Exempt Bonds with the same maturity, coupon and rating may
have different yields when purchased in the open market, while Tax-Exempt Bonds
of the same maturity and coupon with different ratings may have the same yield.

     Generally, however, higher quality Tax-Exempt Bonds produce lower
yields, but are more readily marketable. To protect shareholders' capital under
adverse market conditions, the Fund from time to time may deem it prudent to
purchase higher quality Tax-Exempt Bonds or taxable short-term investments with
a resultant decrease in yield or increase in the proportion of dividend income
taxable to shareholders.

     From time to time, proposals have been introduced before Congress which
would further restrict the issuance of Tax-Exempt Bonds or adversely affect the
Federal income tax consequences of holding such bonds. Similar proposals may be
introduced in the future. It is not possible to determine the effect on the
availability of Tax-Exempt Bonds for investment by the Fund, the value of the
Fund's portfolio if such proposals were enacted, or the Federal income tax
consequences to the Fund's shareholders.

     The Internal Revenue Code affects the excludable nature of interest on
"private activity bonds" and industrial development bonds received by
"substantial users" of facilities financed by such bonds or by "related persons"
of such substantial users. Any person who is such a substantial user or related
person should consult his own tax adviser before purchasing shares of the Fund.

     While the investment objective of the Fund is to earn a high level of
Tax-Exempt interest income, the Fund may temporarily hold cash or invest a
portion of its assets in short-term taxable investments, the interest on which
is subject to Federal income tax. Short-term taxable investments include
securities such as: (1) U.S. Treasury notes, bills, and bonds; (2) obligations
of agencies and instrumentalities of the United States government; and (3) money
market instruments, such as domestic bank certificates of deposit, finance

<PAGE>   174

company and other corporate commercial paper, repurchase agreements and bankers'
acceptances. Occasions for acquiring short-term taxable investments may arise as
a result of market conditions adverse to investments in Tax-Exempt Bonds or
delays in investing the proceeds of sales of Fund shares or sales of portfolio
securities. In addition, the Fund may acquire short-term taxable investments to
be in a position to meet cash requirements for Fund expenses or for the
redemption of shares by Fund shareholders, and thus avoid the necessity of
liquidating long-term portfolio investments. It is not expected that the portion
of the Fund's total assets consisting of short-term taxable investments will
exceed 15%.


CERTAIN INVESTMENT PRACTICES

Repurchase Agreements. A repurchase agreement is a contract under which the Fund
would acquire a security for a relatively short period (usually not more than 7
days) subject to the obligation of the seller to repurchase and the Fund to
resell such security at a fixed time and price (representing the Fund's cost
plus interest). The Fund will enter into repurchase agreements only with member
banks of the Federal Reserve System and with "primary dealers" in U.S.
Government securities. The Adviser will continuously monitor the
creditworthiness of the parties with whom the Fund enters into repurchase
agreements. The Fund has established a procedure providing that the securities
serving as collateral for each repurchase agreement must be delivered to the
Fund's custodian either physically or in book-entry form and that the collateral
must be marked to market daily to ensure that each repurchase agreement is fully
collateralized at all times. In the event of bankruptcy or other default by a
seller of a repurchase agreement, the Fund could experience delays in
liquidating the underlying securities and could experience losses, including the
possible decline in the value of the underlying securities during the period
while the Fund seeks to enforce its rights thereto, possible subnormal levels of
income and lack of access to income during this period, and expense of enforcing
its rights.

Municipal Lease Obligations. A municipal lease is an obligation in the form of a
lease or installment purchase which is issued by a state or local government to
acquire equipment and facilities. Income from such obligations is generally
exempt from state and local taxes in the state of issuance. Municipal leases
frequently involve special risks not normally associated with general obligation
or revenue bonds. Leases and installment purchase or conditional sale contracts
(which normally provide for title to the leased asset to pass eventually to the
governmental issuer) have evolved as a means for governmental issuers to acquire
property and equipment without meeting the constitutional and statutory
requirements for the issuance of debt. The debt issuance limitations are deemed
to be inapplicable because of the inclusion in many leases or contracts of
"non-appropriation" clauses that relieve the governmental issuer of any
obligation to make future payments under the lease or contract unless funds are
appropriated for such purpose by the appropriate legislative body on a yearly or
other periodic basis. In addition, such leases or contracts may be subject to
the temporary abatement of payments in the event the issuer is prevented from
maintaining occupancy of the leased premises or utilizing the leased equipment.
Although the obligations may be secured by the leased equipment or facilities,
the disposition of the property in the event of non appropriation or foreclosure
might prove difficult, time consuming and costly, and result in an
unsatisfactory or delayed repayment of the Fund's original investment.

     Certain municipal lease obligations may be deemed illiquid for the
purpose of the Fund's 15% limitation on investments in illiquid securities.
Other municipal lease obligations acquired by the Fund may be determined by the
Adviser, pursuant to guidelines adopted by the Trustees of the Fund, to be
liquid securities for the purpose of such limitation. In determining the
liquidity of municipal lease obligations, the Adviser will consider a variety of
factors including: (1) the willingness of dealers to bid for the security; (2)
the number of dealers willing to purchase or sell the obligation and the number
of other potential buyers; (3) the frequency of trades or quotes for the
obligation; and (4) the nature of marketplace trades. In addition, the Adviser
will consider factors unique to particular lease obligations affecting the
marketability thereof. These include the general creditworthiness of the issuer,
the importance to the issuer of the property covered by the lease and the
likelihood that the marketability of the obligation will be maintained
throughout the time the obligation is held by the Fund.

Financial Futures Contracts. The Fund may hedge its portfolio by selling
financial futures contracts to offset the effect of expected increases in

<PAGE>   175

interest rates and by purchasing such futures contracts as an offset against the
effect of expected declines in interest rates. Although other techniques could
be used to reduce the Fund's exposure to interest rate fluctuations, the Fund
may be able to hedge its exposure more effectively and perhaps at a lower cost
by using financial futures contracts. The Fund may enter into financial futures
contracts for hedging and speculative purposes to the extent permitted by
regulations of the Commodity Futures Trading Commission ("CFTC").

     In general, the sale of a financial futures contract creates an
obligation of the Fund, as seller, to deliver the specific type of instrument
called for in the contract or the cash value of a securities index at a
specified future time in exchange for receipt of a specified price. The purchase
of a financial futures contract creates an obligation of the Fund, as purchaser,
to take delivery of the specific type of instrument or the cash value of a
securities index at a specified future time in exchange for payment of a
specified price.

     Financial futures contracts have been designed by boards of trade which
have been designated "contract markets" by the CFTC. Futures contracts are
traded on these markets in a manner that is similar to the way a stock is traded
on a stock exchange. The boards of trade, through their clearing corporations,
guarantee that the contracts will be performed. Currently, financial futures
contracts are based on interest rate instruments such as long-term U.S. Treasury
bonds, U.S. Treasury notes, Government National Mortgage Association ("GNMA")
modified pass-through mortgage-backed securities, three-month U.S. Treasury
bills, 90-day commercial paper, bank certificates of deposit and Eurodollar
certificates of deposit and The Municipal Bond Buyer Index. It is expected that
if other financial futures contracts are developed and traded the Fund may
engage in transactions in such contracts.

     Although some financial futures contracts by their terms call for
actual delivery or acceptance of financial instruments, in most cases the
contracts are closed out prior to delivery by offsetting purchases or sales of
matching financial futures contracts (same exchange, underlying security and
delivery month). Other financial futures contracts, such as futures contracts on
securities indices, by their terms call for cash settlements. If the offsetting
purchase price is less than the Fund's original sale price, the Fund realizes a
gain, or if it is more, the Fund realizes a loss. Conversely, if the offsetting
sale price is more than the Fund's original purchase price, the Fund realizes a
gain, or if it is less, the Fund realizes a loss. The transaction costs must
also be included in these calculations. The Fund will pay a commission in
connection with each purchase or sale of financial futures contracts, including
a closing out transaction. For a discussion of the Federal income tax
considerations of trading in financial futures contracts, see the information
under the caption "Tax Status" below.

     At the time the Fund enters into a financial futures contract, it is
required to deposit with its custodian a specified amount of cash or U.S.
government securities, known as "initial margin," ranging upward from 1.1% of
the value of the financial futures contract being traded. The margin required
for a financial futures contract is set by the board of trade or exchange on
which the contract is traded and may be modified during the term of the
contract. The initial margin is in the nature of a performance bond or good
faith deposit on the financial futures contract which is returned to the Fund
upon termination of the contract, assuming all contractual obligations have been
satisfied. The Fund expects to earn interest income on its initial margin
deposits. Each day, the futures contract is valued at the official settlement
price of the board of trade or exchange on which it is traded. Subsequent
payments, known as "variation margin," to and from the broker are made on a
daily basis as the market price of the financial futures contract fluctuates.
This process is known as "mark to market." Variation margin does not represent a
borrowing or lending by the Fund but is instead settlement between the Fund and
the broker of the amount one would owe the other if the financial futures
contract expired. In computing net asset value, the Fund will mark to market its
open financial futures positions.

     Successful hedging depends on a strong correlation between the market
for the underlying securities and the futures contract market for those
securities. There are several factors that will probably prevent this
correlation from being a perfect one, and even a correct forecast of general
interest rate trends may not result in a successful hedging transaction. There
are significant differences between the securities and futures markets which
could create an imperfect correlation between the markets and which could affect
the success of a given hedge. The degree of imperfection of correlation depends

<PAGE>   176

on circumstances such as: variations in speculative market demand for financial
futures and debt securities, including technical influences in futures trading
and differences between the financial instruments being hedged and the
instruments underlying the standard financial futures contracts available for
trading in such respects as interest rate levels, maturities, and
creditworthiness of issuers. The degree of imperfection may be increased where
the underlying debt securities are lower-rated and, thus, subject to greater
fluctuation in price than higher-rated securities.

     A decision as to whether, when and how to hedge involves the exercise
of skill and judgment, and even a well-conceived hedge may be unsuccessful to
some degree because of market behavior or unexpected interest rate trends. The
Fund will bear the risk that the price of the securities being hedged will not
move in complete correlation with the price of the futures contracts used as a
hedging instrument. Although the Adviser believes that the use of financial
futures contracts will benefit the Fund, an incorrect prediction could result in
a loss on both the hedged securities in the Fund's portfolio and the hedging
vehicle so that the Fund's return might have been better had hedging not been
attempted. However, in the absence of the ability to hedge, the Adviser might
have taken portfolio actions in anticipation of the same market movements with
similar investment results but, presumably, at greater transaction costs. The
low margin deposits required for futures transactions permit an extremely high
degree of leverage. A relatively small movement in a futures contract may result
in losses or gains in excess of the amount invested.

     Futures exchanges may limit the amount of fluctuation permitted in
certain futures contract prices during a single trading day. The daily limit
establishes the maximum amount the price of a futures contract may vary either
up or down from the previous day's settlement price at the end of the current
trading session. Once the daily limit has been reached in a futures contract
subject to the limit, no more trades may be made on that day at a price beyond
that limit. The daily limit governs only price movements during a particular
trading day and, therefore, does not limit potential losses because the limit
may work to prevent the liquidation of unfavorable positions. For example,
futures prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some holders of futures contracts to
substantial losses.

     Finally, although the Fund engages in financial futures transactions
only on boards of trade or exchanges where there appears to be an adequate
secondary market, there is no assurance that a liquid market will exist for a
particular futures contract at any given time. The liquidity of the market
depends on participants closing out contracts rather than making or taking
delivery. In the event participants decide to make or take delivery, liquidity
in the market could be reduced. In addition, the Fund could be prevented from
executing a buy or sell order at a specified price or closing out a position due
to limits on open positions or daily price fluctuation limits imposed by the
exchanges or boards of trade. If the Fund cannot close out a position, it will
be required to continue to meet margin requirements until the position is
closed.

Options on Financial Futures Contracts. The Fund may purchase and write
call and put options on financial futures contracts. An option on a futures
contract gives the purchaser the right, in return for the premium paid, to
assume a position in a futures contract at a specified exercise price at any
time during the period of the option. Upon exercise, the writer of the option
delivers the futures contract to the holder at the exercise price. The Fund
would be required to deposit with its custodian initial and variation margin
with respect to put and call options on futures contracts written by it. Options
on futures contracts involve risks similar to the risks relating to transactions
in financial futures contracts. Also, an option purchased by the Fund may expire
worthless, in which case the Fund would lose the premium paid for that option.

Other Considerations. The Fund will engage in futures transactions for bona fide
hedging or speculative purposes to the extent permitted by CFTC regulations. The
Fund will determine that the price fluctuations in the futures contracts and
options on futures used for hedging purposes are substantially related to price
fluctuations in securities held by the Fund or which it expects to purchase.
Except as stated below, the Fund's futures transactions will be entered into for
traditional hedging purposes -- i.e., futures contracts will be sold to protect
against a decline in the price of securities that the Fund owns, or futures
contracts will be purchased to protect the Fund against an increase in the price
of securities it intends to purchase. As evidence of this hedging intent, the

<PAGE>   177

Fund expects that on 75% or more of the occasions on which it takes a long
futures or option position (involving the purchase of futures contracts), the
Fund will have purchased, or will be in the process of purchasing, equivalent
amounts of related securities in the cash market at the time when the futures
or, option position is closed out. However, in particular cases, when it is
economically advantageous for a Fund to do so, a long futures position may be
terminated or an option may expire without the corresponding purchase of
securities.

     As an alternative to literal compliance with the bona fide hedging
definition, a CFTC regulation permits the Fund to elect to comply with a
different test, under which the aggregate initial margin and premiums required
to establish speculative positions in futures contracts and options on futures
will not exceed 5% of the net asset value of the Fund's portfolio, after taking
into account unrealized profits and losses on any such positions and excluding
the amount by which such options were in-the-money at the time of purchase. The
Fund will engage in transactions in futures contracts only to the extent such
transactions are consistent with the requirements of the Internal Revenue Code
for maintaining its qualification as a regulated investment company for Federal
income tax purposes.

     The Fund's investment objective and the investment policies and
practices described above are not fundamental (except where noted) and may be
changed by the Trustees without shareholder approval.

     When the fund purchases a financial futures contract, or writes a put
option or purchases a call option thereon, cash and high grade liquid debt
securities will be deposited in a segregated account with the Fund's custodian
in an amount that together with the amount of initial and variation margin held
in the account of its broker, equals the market value of the futures contract.


INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions:

The following investment restrictions will not be changed without approval of a
majority of outstanding voting securities which, as used in the Prospectus and
the Statement of Additional Information, means approval of the lesser of (1) the
holders of 67% or more of the shares represented at a meeting if the holders of
more than 50% of the outstanding shares are present in person or by proxy or (2)
the holders of more than 50% of the outstanding shares.

         The Fund observes the following fundamental investment restrictions.

         The Fund may not:

(1)      Issue senior securities, except as permitted by paragraphs (2) and (7)
         below. For purposes of this restriction, the issuance of shares of
         beneficial interest in multiple classes or series, the purchase or sale
         of options, futures contracts and options on futures contracts, forward
         commitments, and repurchase agreements entered into in accordance with
         the Fund's investment policies, and the pledge, mortgage or
         hypothecation of the Fund's assets within the meaning of paragraph (3)
         below are not deemed to be senior securities.

(2)      Borrow money, except from banks as a temporary measure where such
         borrowings would not exceed 5% of the market value of the Fund's total
         assets at the time each such borrowing is made.

(3)      Pledge, mortgage, or hypothecate its assets, except to secure
         indebtedness permitted by paragraph (2) above and then only if such
         pledging, mortgaging or hypothecating does not exceed 10% of the Fund's
         total assets taken at cost.

(4)      Act as an underwriter, except to the extent that, in connection with
         the disposition of portfolio investments, the Fund may be deemed to be
         an underwriter for purposes of the Securities Act of 1933. The Fund may
         also participate as part of a group in bidding for the purchase of
         Tax-Exempt Bonds directly from an issuer in order to take advantage of
         the lower purchase price available to members of such groups.

(5)      Purchase real estate or any interest therein, but this restriction
         shall not prevent the Fund from investing in Tax-Exempt Bonds secured
         
<PAGE>   178
         by real estate or interests therein.

(6)      Make loans, except that the Fund (1) may lend portfolio securities in
         accordance with the Fund's investment policies in an amount up to 33
         1/3% of the Fund's total assets taken at market value, (2) enter into
         repurchase agreements, and (3) purchase all or a portion of an issue of
         debt securities, bank loan participation interests, bank certificates
         of deposit, bankers' acceptances, debentures or other securities,
         whether or not the purchase is made upon the original issuance of the
         securities.

(7)      Purchase or sell commodities or commodity contracts or puts, calls or
         combinations of both, except options on securities, securities indices,
         currency and other financial instruments, futures contracts on
         securities, securities indices, currency and other financial
         instruments and options on such futures contracts, forward commitments,
         interest rate swaps, caps and floors, securities index put or call
         warrants and repurchase agreements entered into in accordance with the
         Fund's investment policies.

(8)      Purchase any security (other than securities issued or guaranteed by
         the U.S. Government, its agencies or instrumentalities and repurchase
         agreements collateralized by such securities) if, as a result: (a) more
         than 5% of its total assets would be invested in the securities of any
         one issuer, or (b) the Fund would own more than 10% of the voting
         securities of any one issuer. For purposes of this paragraph 8, each
         governmental unit (state, county, city, for example) and each
         subdivision, agency or instrumentality thereof and each multi-member
         agency of which any of them is a member shall be considered a separate
         issuer.

(9)      Purchase securities of an issuer conducting its principal activity in
         any particular industry if immediately after such purchase the value of
         the Fund's investments in all issuers in this industry would exceed 25%
         of its total assets taken at market value. (Tax-Exempt Bonds and
         securities issued or guaranteed by the United States government and its
         agencies and instrumentalities are not subject to this limitation.)

(10)     Purchase securities other than Tax-Exempt Bonds and short-term taxable
         investments, as those terms are defined in this Statement of Additional
         Information.

Non fundamental Investment Restrictions

The following restrictions are designated as non fundamental and may be
changed by the Trustees without shareholder approval.

         The Fund may not:

(a)      Participate on a joint-and-several basis in any securities trading
         account. The "bunching" of orders for the sale or purchase of
         marketable portfolio securities with other accounts under the
         management of the Adviser to save commissions or to average prices
         among them and the participation of the Fund as a part of a group
         bidding for the purchase of Tax-Exempt Bonds as permitted by
         fundamental investment restriction No. 4 are not deemed to result in a
         securities trading account.

(b)      Purchase securities on margin or make short sales unless by virtue of
         its ownership of other securities, the Fund has the right to obtain
         securities equivalent in kind and amount to the securities sold and, if
         the right is conditional, the sale is made upon the same conditions,
         except that the Fund may obtain such short-term credits as may be
         necessary for the clearance of purchases and sales of securities.

(c)      Purchase a security if, as a result, (i) more than 10% of the Fund's
         total assets would be invested in securities of closed-end investment
         companies, (ii) such purchase would result in more than 3% of the total
         outstanding voting securities of any one such closed-end investment
         company being held by the Fund, or (iii) more than 5% of the Fund's
         total assets would be invested in any one such closed-end investment
         company. The Fund will not purchase the securities of any open-end
         investment company, except in a merger, consolidation or other
         reorganization.

<PAGE>   179
(d)      Purchase securities of any issuer which, together with any predecessor,
         has a record of less than three years' continuous operations prior to
         the purchase if such purchase would cause investments of the Fund in
         all such issuers to exceed 5% of the value of the total assets of the
         Fund. (This limitation does not apply to securities that are issued or
         guaranteed by the United States government and its agencies or
         instrumentalities or that are secured by the pledge of the faith,
         credit and taxing power of any entity authorized to issue Tax-Exempt
         Bonds.)

(e)      Invest for the purpose of exercising control over or management of any
         company.

(f)      Purchase warrants of any issuer, if, as a result of such purchases,
         more than 2% of the value of the Fund's total assets would be invested
         in warrants which are not listed on the New York Stock Exchange or the
         American Stock Exchange or more than 5% of the value of the total
         assets of the Fund would be invested in warrants generally, whether or
         not so listed. For these purposes, warrants are to be valued at the
         lesser of cost or market, but warrants acquired by the Fund in units
         with or attached to debt securities shall be deemed to be without
         value.

(g)      Knowingly purchase or retain securities of an issuer if one or more of
         the Trustees or officers of the Fund or directors or officers of the
         Adviser or any investment management subsidiary of the Adviser
         individually owns beneficially more than 0.5%, and together own
         beneficially more than 5%, of the securities of such issuer.

(h)      Purchase or sell interests in real estate limited partnerships or in
         oil, gas or other mineral leases or exploration or development
         programs; however, this policy will not prohibit the acquisition of
         securities of companies engaged in the production or transmission of
         oil, gas or other minerals.

(i)      Write, purchase or sell puts, calls or combinations thereof except in
         accordance with its investment objective and policies. The Fund will
         not purchase or write options on equity securities.

(j)      Knowingly purchase any security that is subject to legal or contractual
         delays in or restrictions on resale.

(k)      Notwithstanding any investment restriction to the contrary, the Fund
         may, in connection with the John Hancock Group of Funds Deferred
         Compensation Plan for Independent Trustees/Directors, purchase
         securities of other investment companies within the John Hancock Group
         of Funds provided that, as a result, (i) no more than 10% of the Fund's
         assets would be invested in securities of all other investment
         companies, (ii) such purchase would not result in more than 3% of the
         total outstanding voting securities of any one such investment company
         being held by the Fund and (iii) no more than 5% of the Fund's assets
         would be invested in any one such investment company.

     In order to permit the sale of shares of the Fund in certain states,
the Trustees may, in their sole discretion, adopt restrictions on investment
policy more restrictive than those described above. Should the Trustees
determine that any such restrictive policy is no longer in the best interest of
the Fund and its shareholders, the Fund may cease offering shares in the state
involved and the Trustees may revoke such restrictive policy. Moreover, if the
states involved shall no longer require any such restrictive policy, the
Trustees may, at their sole discretion, revoke such policy.

     If a percentage restriction on investment or utilization of assets as
set forth above is adhered to at the time an investment is made, a later change
in percentage resulting from changes in the values or the total costs of the
Fund's assets will not be considered a violation of the restriction.

INVESTMENT ADVISORY AND OTHER SERVICES

     As described in the Prospectus, the Fund receives its investment advice
from the Adviser. Investors should refer to the Prospectus for a description of
certain information concerning the investment management contract. Each of the
Trustees and principal officers of the Fund who is also an affiliated person of
the Adviser is named above, together with the capacity in which such person is
affiliated with the Fund and the Adviser.

     As described in the Fund's Prospectus under the caption "Organization
and Management of the Fund," the Fund has entered into an investment management
contract with the Adviser. Under the investment management contract the Adviser
provides the Fund with (i) a continuous investment program, consistent with the
Fund's stated investment objective and policies (ii) supervision of all aspects
of the Fund's operations except those that are delegated to a custodian,
transfer agent or other agent and (iii) such executive administrative and
clerical personnel, officers and equipment as are necessary for the conduct of
its business. The Adviser is responsible for the management of the Fund's
portfolio assets.

<PAGE>   186
     Securities held by the Fund may also be held by other funds or
investment advisory clients for which the Adviser or its affiliates provide
investment advice. Because of different investment objectives or other factors,
a particular security may be bought for one or more funds or clients when one or
more other funds or clients are selling the same security. If opportunities for
purchase or sale of securities by the Adviser for the Fund or for other funds or
clients for which the Adviser renders investment advice arise for consideration
at or about the same time, transactions in such securities will be made, insofar
as feasible, for the respective funds or clients in a manner deemed equitable to
all of them. To the extent that transactions on behalf of more than one client
of the Adviser or its affiliates may increase the demand for securities being
purchased or the supply of securities being sold, there may be an adverse effect
on price.

     No person other than the Adviser and its directors and employees
regularly furnishes advice to the Fund with respect to the desirability of the
Fund's investing in, purchasing or selling securities. The Adviser may from time
to time receive statistical or other similar factual information, and
information regarding general economic factors and trends, from the Life
Insurance Company and its affiliates.


     Under the terms of the investment management contract with the Fund,
the Adviser provides the Fund with office space, supplies and other facilities
required for the business of the Fund. The Adviser pays the compensation of all
other officers and employees of the Fund, and pays the expenses of clerical
services relating to the administration of the Fund.

     All expenses which are not specifically paid by the Adviser and which
are incurred in the operation of the Fund (including fees of Trustees of the
Fund who are not "interested persons", as such term is defined in the Investment
Company Act, but excluding certain distribution related activities required to
be paid by the Adviser or John Hancock Funds) and the continuous public offering
of the shares of the Fund are borne by the Fund. Class expenses properly
allocable to either Class A shares or Class B shares will be borne exclusively
by such class of shares, subject to conditions set forth in a private letter
ruling that the Trust has received from the Internal Revenue Service relating to
its multiple-class structure.

     As discussed in the Prospectus and as provided by the investment
management contract, the Fund pays the Adviser monthly an investment management
fee, which is accrued daily, based on a stated percentage of the average of the
daily net assets of the Fund as follows:

<TABLE>
              Net Asset Value                           Annual Rate
              ---------------                           -----------
              <S>                                       <C>
              First $500,000,000                        0.55%
              Next  $500,000,000                        0.50%
              Amount over $1,000,000,000                0.45%

</TABLE>

     From time to time, the Adviser may reduce its fee or make other
arrangements to limit the Fund's expenses to a specified percentage of average
daily net assets. The Adviser retains the right to re-impose a fee and recover
any other payments to the extent that, at the end of any fiscal year, the Fund's
annual expenses fall below this limit.

     On December 31, 1994, the net assets of the Fund were $471,488,790. For
the years ended December 31, 1992, 1993 and 1994, the Adviser received fees of
$2,179,523, $2,460,892 and $2,763,233 respectively. The 1992 and 1993 advisory
fee figures reflects the different advisory fee schedule that was in effect
before January 3, 1994.

     If the total of all ordinary business expenses of the Fund for any
fiscal year exceeds limitations prescribed in any state in which shares of the
Fund are qualified for sale, the fee payable to the Adviser will be reduced to
the extent required by these limitations. At this time, the most restrictive
limits on expenses applicable to the Fund imposed by a state require that
expenses charged to the Fund in any fiscal year not exceed 2 1/2% of the first
$30,000,000 of the Fund's average net asset value, 2% of the next $70,000,000 of
such assets and 1 1/2% of the remaining average net asset value. When
calculating the above limit, the Fund may exclude interest, brokerage
<PAGE>   187

commissions and extraordinary expenses.

     Pursuant to its investment management contract, the Adviser is not
liable to the Fund or its shareholders for any error of judgment or mistake of
law or for any loss suffered by the Fund in connection with the matters to which
the investment management contract relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its duties or from reckless disregard by the Adviser of its
obligations and duties under the investment management contract.

     The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts
02199-7603, was organized in 1968 and presently has more than $13 billion in
assets under management in its capacity as investment adviser to the Fund and
the other mutual funds and publicly traded investment companies in the John
Hancock group of funds having a combined total of over 1,060,000 shareholders.
The Adviser is an affiliate of the Life Insurance Company, one of the most
recognized and respected financial institutions in the nation. With total assets
under management of $80 billion, the Life Insurance Company is one of the ten
largest life insurance companies in the United States, and carries Standard &
Poor's and A.M. Best's highest ratings. Founded in 1862, the Life Insurance
Company has been serving clients for over 130 years.

     Under the investment management contract, the Fund may use the name
"John Hancock" or any name derived from or similar to it only for so long as the
contract or any extension, renewal or amendment thereof remains in effect. If
the contract is no longer in effect, the Fund (to the extent that it lawfully
can) will cease to use such a name or any other name indicating that it is
advised by or otherwise connected with the Adviser. In addition, the Adviser or
the Life Insurance Company may grant the non-exclusive right to use the name
"John Hancock" or any similar name to any other corporation or entity, including
but not limited to any investment company of which the Life Insurance Company or
any subsidiary or affiliate thereof or any successor to the business of any
subsidiary or affiliate thereof shall be the investment adviser.

     The investment management contract and the distribution contract
discussed below continue in effect from year to year if approved annually by
vote of a majority of the Fund's Trustees who are not interested persons of one
of the parties to the contract, cast in person at a meeting called for the
purpose of voting on such approval, and by either the Fund's Trustees or the
holders of a majority of the Fund's outstanding voting securities. The contract
automatically terminates upon assignment. The contract may be terminated without
penalty on 60 days' notice at the option of either party to the contract or by
vote of a majority of the outstanding voting securities of the Fund.


DISTRIBUTION CONTRACT

     The Fund has a distribution contract with John Hancock Funds. Under the
contract, John Hancock Funds is obligated to use its best efforts to sell shares
on behalf of the Fund. Shares of the Fund are also sold by selected
broker-dealers (the "Selling Brokers") which have entered into selling agency
agreements with John Hancock. John Hancock accepts orders for the purchase of
the shares of the Fund which are continually offered at net asset value next
determined plus applicable sales charge. In connection with the sale of Class A
and Class B shares, John Hancock Funds and Selling Brokers receive compensation
in the form of a sales charge imposed, in the case of Class A shares, at the
time of sale or, in the case of Class B shares, on a deferred basis. The sales
charges are discussed further in the Fund's Class A and Class B Prospectus.

     The Fund's Trustees adopted Distribution Plans with respect to Class A
and Class B shares pursuant to Rule 12b-1 under the Investment Company Act.
Under the Class A and Class B Plans, the Fund will pay distribution and service
fees at an aggregate annual rate of up to 0.30% and 1.00%, respectively, of the
Fund's average daily net assets. However, the amount of the service fee will not
exceed 0.25% of the Fund's average daily net assets attributable to each class
of shares. The distribution fees reimburse John Hancock Funds for its
distribution costs incurred in the promotion of sales of shares of the Fund, and
the service fees compensate Selling Brokers for providing personal and account
maintenance services to shareholders. In the event that John Hancock Funds is
not fully reimbursed for expenses incurred by it under the Class B Plan in any
fiscal year, John Hancock Funds may carry these expenses forward, provided

<PAGE>   188

however, that the Trustees may terminate the Class B Plan and thus the Fund's
obligation to make further payments at any time. Accordingly, the Fund does not
treat unreimbursed expenses relating to the Class B shares as a liability of the
Fund. The Plans were approved by a majority of the voting securities of the
applicable class of the Fund. The Plans with all amendments were approved by a
majority of the Trustees, including a majority of the Trustees who are not
interested persons of the Fund and who have no direct or indirect financial
interest in the operation of the Plans (the "Independent Trustees"), by votes
cast in person at meetings called for the purpose of voting on such Plans.

     Pursuant to the Plans, at least quarterly, John Hancock Funds provides
the Fund with a written report of the amounts expended under the Plans and the
purpose for which expenditures were made. The Trustees review these reports on a
quarterly basis.

     During the fiscal year ended December 31, 1994 the Funds paid Investor
Services the following amounts of expenses with respect to the Class A shares
and Class B shares of each of the Funds:

</TABLE>


     Each of the Plans provides that it will continue in effect only so long
as its continuance is approved at least annually by a majority of both the
Trustees and the Independent Trustees. Each of the Plans provides that it may be
terminated without penalty (a) by vote of a majority of the Independent
Trustees, (b) by a majority of the Fund's outstanding shares of the applicable
class upon 60 days' written notice to John Hancock Funds, and (c) automatically
in the event of assignment. Each of the Plans further provides that it may not
be amended to increase the maximum amount of the fees for the services described
therein without the approval of a majority of the outstanding shares of the
class of the Fund which has voting rights with respect to the Plans. And
finally, each of the Plans provides that no material amendment to the Plan will,
in any event, be effective unless it is approved by a vote of the Trustees and
the Independent Trustees. In adopting the Plan, the Trustees concluded that, in
their judgment, there is a reasonable likelihood that each Plan will benefit the
holders of the applicable class of shares of the Fund.
     When the Fund seeks an Independent Trustee to fill a vacancy or as a
nominee for election by shareholders, the selection or nomination of the
Independent Trustee is, under resolutions adopted by the Trustees
contemporaneously with their adoption of the Plans, committed to the discretion
of the Committee on Administration of the Trustees. The members of the Committee
on Administration are all Independent Trustees and are identified in this
Statement of Additional Information under the heading "Those Responsible for
Management."


NET ASSET VALUE

     For purposes of calculating the net asset value ("NAV") of a Fund's
shares, the following procedures are utilized wherever applicable. Debt
investment securities are valued on the basis of valuations furnished by a
principal market maker or a pricing service, both of which generally utilize
electronic data processing techniques to determine valuations for normal
institutional size trading units of debt securities without exclusive reliance
upon quoted prices.

     Short-term debt investments which have a remaining maturity of 60 days
or less are generally valued at amortized cost which approximates market value.
If market quotations are not readily available or if in the opinion of the

<PAGE>   189

Adviser any quotation or price is not representative of true market value, the
fair value of the security may be determined in good faith in accordance with
procedures approved by the Trustees.

     A Fund will not price its securities on the following national
holidays: New Year's Day; Presidents' Day; Good Friday; Memorial Day;
Independence Day; Labor Day; Thanksgiving Day; and Christmas Day.


INITIAL SALES CHARGE ON CLASS A SHARES

     The sales charges applicable to purchases of Class A shares of the Fund
are described in the Fund's Class A and Class B Prospectus. Methods of obtaining
reduced sales charges referred to generally in the Prospectus are described in
detail below. In calculating the sales charge applicable to current purchases of
Class A shares, the investor is entitled to cumulate current purchases with the
greater of the current value (at offering price) of the Class A shares of the
Fund, or if Investor Services is notified by the investor's dealer or the
investor at the time of the purchase, the cost of the Class A shares owned.

Combined Purchases. In calculating the sales charge applicable to purchases of
Class A shares made at one time, the purchases will be combined if made by (a)
an individual, his spouse and their children under the age of 21, purchasing
securities for his or their own account, (b) a trustee or other fiduciary
purchasing for a single trust, estate or fiduciary account and (c) certain
groups of four or more individuals making use of salary deductions or similar
group methods of payment whose funds are combined for the purchase of mutual
fund shares. Further information about combined purchases, including certain
restrictions on combined group purchases, is available from Investor Services or
a selling Broker's representative.

Without Sales Charge. As described in the Class A and Class B Prospectus, Class
A shares of the Fund may be sold without a sales charge to certain persons
described in the Prospectus.

Accumulation Privilege. Investors (including investors combining purchases) who
are already Class A shareholders may also obtain the benefit of the reduced
sales charge by taking into account not only the amount then being invested but
also the purchase price or value of the Class A shares already held by such
person.

Combination Privilege. Reduced sales charges (according to the schedule set
forth in the Class A and Class B Prospectus) also are available to an investor
based on the aggregate amount of his concurrent and prior investments in Class A
shares of the Fund and shares of all other John Hancock funds which carry a
sales charge.

Letter of Intention. Reduced sales charges are also applicable to investments
made over a specified period pursuant to a Letter of Intention (the "LOI"),
which should be read carefully prior to its execution by an investor. Such an
investment (including accumulation and combinations) must aggregate $100,000 or
more invested during a period of thirteen months from the date of the LOI or
from a date within ninety days prior thereto, upon written request to Investor
Services. The sales charge applicable to all amounts invested under the LOI is
computed as if the aggregate amount intended to be invested had been invested
immediately. If such aggregate amount is not actually invested, the difference
in the sales charge actually paid and the sales charge payable had the LOI not
been in effect is due from the investor. However, for the purchases actually
made within the thirteen-month period the sales charge applicable will not be
higher than that which would have applied (including accumulations and
combinations) had the LOI been for the amount actually invested.

     The LOI authorizes Investor Services to hold in escrow sufficient Class
A shares (approximately 5% of the aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the thirteen-month period, at which
time the escrow shares will be released. If the total investment specified in
the LOI is not completed, the Class A shares held in escrow may be redeemed and
the proceeds used as required to pay such sales charge as may be due. By signing
the LOI, the investor authorizes Investor Services to act as his
attorney-in-fact to redeem any escrowed shares and adjust the sales charge, if
necessary. An LOI does not constitute a binding commitment by an investor to

<PAGE>   190

purchase, or by the Fund to sell, any additional Class A shares and may be
terminated at any time.


DEFERRED SALES CHARGE ON CLASS B SHARES

     Investments in Class B shares are purchased at net asset value per
share without the imposition of an initial sales charge so that the Fund will
receive the full amount of the purchase payment.

Contingent Deferred Sales Charge.  Class B shares which are redeemed within six
years of purchase will be subject to a contingent deferred sales charge ("CDSC")
at the rates set forth in the Class A and Class B Prospectus as a percentage of
the dollar amount subject to the CDSC. The charge will be assessed on an amount
equal to the lesser of the current market value or the original purchase cost of
the Class B shares being redeemed. Accordingly, no CDSC will be imposed on
increases in account value above the initial purchase prices, including Class B
shares derived from reinvestment of dividends or capital gains distributions.

     The amount of the CDSC, if any, will vary depending on the number of
years from the time of payment for the purchase of Class B shares until the time
of redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchases of shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month.

     Proceeds from the CDSC are paid to John Hancock Funds and are used in
whole or in part by John Hancock Funds to defray its expenses related to
providing distribution-related services to the Fund in connection with the sale
of the Class B shares, such as the payment of compensation to select Selling
Brokers for selling Class B shares. The combination of the CDSC and the
distribution and service fees facilitates the ability of the Fund to sell the
Class B shares without a sales charge being deducted at the time of the
purchase. See the Class A and Class B Prospectus for additional information
regarding the CDSC.

SPECIAL REDEMPTIONS

     Although it would not normally do so, the Fund has the right to pay the
redemption price of shares of the Fund in whole or in part in portfolio
securities as prescribed by the Trustees. If the shareholder were to sell
portfolio securities received in this fashion he would incur a brokerage charge.
Any such securities would be valued for the purposes of making such payment at
the same value as used in determining net asset value. The Fund has, however,
elected to be governed by Rule 18f-1 under the Investment Company Act. Under
that rule, the Fund must redeem its shares for cash except to the extent that
the redemption payments to any shareholder during any 90-day period would exceed
the lesser of $250,000 or 1% of the Fund's net asset value at the beginning of
such period.


ADDITIONAL SERVICES AND PROGRAMS

Exchange Privilege. As described more fully in the Prospectus, the Fund permits
exchanges of shares of any class of the Fund for shares of the same class in any
other John Hancock fund offering that class.

Systematic Withdrawal Plan. As described briefly in the Class A and Class B
Prospectus, the Fund permits the establishment of a Systematic Withdrawal Plan.
Payments under this plan represent proceeds arising from the redemption of Fund
shares. Since the redemption price of Fund the shares may be more or less than
the shareholder's cost, depending upon the market value of the securities owned
by the Fund at the time of redemption, the distribution of cash pursuant to this
plan may result in realization of gain or loss for purposes of Federal, state
and local income taxes. The maintenance of a Systematic Withdrawal Plan
concurrently with purchases of additional Class A or Class B shares of the Fund
could be disadvantageous to a shareholder because of the initial sales charge
payable on such purchases of Class A shares and the CDSC imposed on redemptions
of Class B shares and because redemptions are taxable events. Therefore, a
shareholder should not purchase Fund shares at the same time as a Systematic

<PAGE>   191

Withdrawal Plan is in effect. The Fund reserves the right to modify or
discontinue the Systematic Withdrawal Plan of any shareholder on 30 days' prior
written notice to such shareholder, or to discontinue the availability of such
plan in the future. The shareholder may terminate the plan at any time by giving
proper notice to Investor Services.

Monthly Automatic Accumulation Program ("MAAP"). This program is explained fully
in the Fund's Class A and Class B Prospectus and the Account Privileges
Application. The program, as it relates to automatic investment checks, is
subject to the following conditions:

     The investments will be drawn on or about the day of the month
indicated.

     The privilege of making investments through the Monthly Automatic
Accumulation Program may be revoked by Investor Services without prior notice if
any investment is not honored by the shareholder's bank. The bank shall be under
no obligation to notify the shareholder as to the non-payment of any check.

     The program may be discontinued by the shareholder either by calling
Investor Services or upon written notice to Investor Services which is received
at least five (5) business days prior to the due date of any investment.

Reinvestment Privilege. A shareholder who has redeemed Fund shares may, within
120 days after the date of redemption, reinvest without payment of a sales
charge any part of the redemption proceeds in shares of the same class of the
Fund or another John Hancock mutual fund, subject to the minimum investment
limit in that fund. The proceeds from the redemption of Class A shares may be
reinvested at net asset value without paying a sales charge in Class A shares of
the Fund or in Class A shares of another John Hancock fund. If a CDSC was paid
upon a redemption, a shareholder may reinvest the proceeds from that redemption
at net asset value in additional shares of the class from which the redemption
was made. The shareholder's account will be credited with the amount of any CDSC
charged upon the prior redemption and the new shares will continue to be subject
to the CDSC. The holding period of the shares acquired through reinvestment
will, for purposes of computing the CDSC payable upon a subsequent redemption,
include the holding period of the redeemed shares. The Fund may modify or
terminate the reinvestment privilege at any time.

     A redemption or exchange of Fund shares is a taxable transaction for
Federal income tax purposes even if the reinvestment privilege is exercised, and
any gain or loss realized by a shareholder on the redemption or other
disposition of Fund shares will be treated for tax purposes as described under

     The Trustees of the Fund are responsible for the management and
supervision of the Fund. The Declaration of Trust permits the Trustees to issue
an unlimited number of full and fractional shares of beneficial interest without
par value. Under the Declaration of Trust, the Trustees have the authority to
create and classify shares of beneficial interest in separate series, without
further action by shareholders. As of the date of this Statement of Additional
Information, the Trustees have authorized shares of the Fund but not any
additional series, although they may do so in the future. The Declaration of
Trust also authorizes the Trustees to classify and reclassify the shares of the
Trust, or any other series of the Trust, into one or more classes. As of the
date of this Statement of Additional Information, the Trustees have authorized
the issuance of two classes of shares of the Fund, designated as Class A and
Class B.

     The shares of each class of the Fund represent an equal proportionate
interest in the aggregate net assets attributable to that class of the Fund.
Class A shares and Class B shares of the Fund will be sold exclusively to
members of the public (other than the institutional investors described in the
Prospectuses) at net asset value. A sales charge will be imposed either at the
time of the purchase, for Class A shares, or on a contingent deferred basis, for
Class B shares. For Class A shares, no sales charge is payable at the time of
purchase on investments of $1 million or more, but for such investments a
contingent deferred sales charge may be imposed in the event of certain
redemption transactions within one year of purchase

<PAGE>   192


     Holders of Class A and Class B shares each have certain exclusive
voting rights on matters relating to their respective Rule 12b-1 distribution
plans. The different classes of the Fund may bear different expenses relating to
the cost of holding shareholder meetings necessitated by the exclusive voting
rights of any class of shares.

     Dividends paid by the Fund, if any, with respect to each class of
shares will be calculated in the same manner, at the same time and on the same
day and will be in the same amount, except that (i) Class B shares will pay
higher distribution and service fees than Class A shares and (ii) each of Class
A shares and Class B shares will bear any class expenses properly allocable to
such class of shares, subject to the conditions set forth in a private letter
ruling that the Fund has received from the Internal Revenue Service relating to
its multiple-class structure. Similarly, the net asset value per share may vary
depending whether Class A shares or Class B shares are purchased. In the event
of liquidation, shareholders of each class are entitled to share pro rata in the
net assets of the Fund available for distribution to these shareholders. Shares
entitle their holders to one vote per share, are freely transferable and have no
preemptive subscription or conversion rights. When issued, shares are fully paid
and non-assessable, except as set forth below.

     Unless otherwise required by the Investment Company Act or the
Declaration of Trust, the Fund has no intention of holding annual meetings of
shareholders. Fund shareholders may remove a Trustee by the affirmative vote of
at least two-thirds of the Fund's outstanding shares and the Trustees shall
promptly call a meeting for such purpose when requested to do so in writing by
the record holders of not less than 10% of the outstanding shares of the Fund.
Shareholders may, under certain circumstances, communicate with other
shareholders in connection with requesting a special meeting of shareholders.
However, at any time that less than a majority of the Trustees holding office
were elected by the shareholders, the Trustees will call a special meeting of
shareholders for the purpose of electing Trustees.

     Under Massachusetts law, shareholders of a Massachusetts business trust
could, under certain circumstances, be held personally liable for acts or
obligations of the trust. However, the Fund's Declaration of Trust contains an
express disclaimer of shareholder liability for acts, obligations or affairs of
the Fund. The Declaration of Trust also provides for indemnification out of the
Fund's assets for all losses and expenses of any shareholder held personally
liable by reason of being or having been a shareholder. Liability is therefore
limited to circumstances in which the Fund itself would be unable to meet its
obligations, and the possibility of this occurrence is remote.


TAX STATUS

     The Fund has qualified and elected and intends to continue to be
treated as a "regulated investment company" under Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"). As such and by complying with the
applicable provisions of the Code regarding the sources of its income, the
timing of its distributions and the diversification of its assets, the Fund will
not be subject to Federal income tax on tax-exempt income or taxable income
(including net realized capital gains) distributed to shareholders at least
annually in accordance with the timing requirements of the Code.

     The Fund will be subject to a four percent nondeductible Federal excise
tax on certain taxable amounts not distributed (and not treated as having been
distributed) on a timely basis in accordance with annual minimum distribution
requirements. The Fund intends under normal circumstances to avoid liability for
such tax by satisfying such distribution requirements.

     Distributions from the Fund's current or accumulated earnings and
profits ("E&P"), as computed for Federal income tax purposes, will be taxable as
described in the Fund's Prospectus whether taken in shares or in cash. Amounts
that are not allowable as a deduction in computing taxable income, including
expenses associated with earning tax-exempt interest income, do not reduce
current E&P for this purpose. Distributions, if any, in excess of E&P will
constitute a return of capital, which will first reduce an investor's tax basis
in Fund shares and thereafter (after such basis is reduced to zero) will

<PAGE>   193

generally give rise to capital gains. Taxable distributions include
distributions from income or gains from the Fund's taxable investments,
including repurchase agreements, securities loans, options and futures, any
dispositions of the rights to acquire when-issued securities prior to issuance,
income attributable to accrued market discount, and a portion of the discount
from certain stripped tax-exempt obligations or their coupons. Corporate
shareholders of the Fund will not be entitled to the corporate dividends
received deduction for any of the Fund's dividends or other distributions.
Shareholders electing to receive distributions in the form of additional shares
will have a cost basis for Federal income tax purposes in each share so received
equal to the amount of cash that they would have received had they elected to
receive the distribution in cash, dividend by the number of shares received.
     Distributions of the tax-exempt interest (i.e., interest excludable
from gross income under the Code) the Fund earns will be treated as tax-exempt
interest in shareholders' hands provided that, as anticipated, the Fund
qualifies as a regulated investment company, has at least 50% of the value of
its total assets at the end of each quarter of its taxable year invested in
tax-exempt obligations, and properly designates such distributions as
"exempt-interest dividends."

     Interest income from certain types of tax-exempt bonds that are private
activity bonds in which the Fund may invest is treated as an item of tax
preference for purposes of the Federal alternative minimum tax. To the extent
that the Fund invests in these types of tax-exempt bonds, shareholders will be
required to treat as an item of tax preference for Federal alternative minimum
tax purposes that part of the Fund's exempt-interest dividends which is derived
from interest on these tax-exempt bonds. Further, exempt-interest dividends
derived from tax-exempt interest income that is not an item of tax preference
will be included in corporate "adjusted current earnings" for purposes of
computing the alternative minimum tax liability, if any, of corporate
shareholders of the Fund.

     The amount of net realized capital gains, if any, in any given year
will vary depending upon the Adviser's current investment strategy and whether
the Adviser believes it to be in the best interest of the Fund to dispose of
portfolio securities that will generate capital gains or to enter into options
or futures transactions. At the time of an investor's purchase of Fund shares, a
portion of the purchase price is often attributable to realized or unrealized
appreciation in the Fund's portfolio or undistributed taxable income of the
Fund. Consequently, subsequent distributions from such appreciation or income
may be taxable to such investor even if the net asset value of the investor's
shares is, as a result of the distributions, reduced below the investor's cost
for such shares, and the distributions in reality represent a return of a
portion of the purchase price.

     Upon a redemption of shares (including by exercise of the exchange
privilege) a shareholder will ordinarily realize a taxable gain or loss
depending upon his basis in his shares. This gain or loss will be treated as
capital gain or loss if the shares are capital assets in the shareholder's hands
and will be long-term or short-term, depending upon the shareholder's tax
holding period for the shares. Shareholders should consider, in determining the
timing of any redemption, that the portion of a redemption distribution
attributable to tax-exempt interest income that the Fund has accrued but not yet
declared as a dividend will be treated as part of the proceeds of the redemption
of shares in determining any gain or loss, rather than as tax-exempt interest.
Consequently, redeeming shares shortly before the anticipated record date of a
forthcoming exempt-interest dividend may result in the realization of a larger
gain (or a smaller loss) than if the redemption had occurred shortly after
receipt of the exempt-interest dividend, and the effect may be to convert an
amount that would have been tax-exempt (the accrued tax-exempt interest) into an
amount that is taxable as part of the redemption proceeds. A sales charge paid
in purchasing Class A shares of the Fund cannot be taken into account for
purposes of determining gain or loss on the redemption or exchange of these
shares within ninety (90) days after their purchase to the extent Class A shares
of the Fund or another John Hancock fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privileges.
This disregarded charge will result in an increase in the shareholder's tax
basis in the shares subsequently acquired. Also, any loss realized on a
redemption or exchange may be disallowed for tax purposes to the extent the
shares disposed of are replaced with other shares of the Fund within a period of

<PAGE>   194

sixty-one (61) days beginning thirty (30) days before and ending thirty (30)
days after the shares are disposed of, such as pursuant to the Dividend
Reinvestment Plan. In such a case, the basis of the shares acquired will be
adjusted to reflect the disallowed loss. Any loss realized upon the redemption
of shares with a tax holding period of six months or less will be disallowed to
the extent of any exempt-interest dividends received with respect to such
shares, and any such loss not disallowed will be treated as a long-term capital
loss to the extent of any amounts treated as distributions of long-term capital
gain with respect to such shares.

     Although its present intention is to distribute all net capital gains
annually, if any, the Fund reserves the right to retain and reinvest all or any
portion of the excess, as computed for Federal income tax purposes, of net
long-term capital gain over net short-term capital loss in any year. The Fund
will not in any event distribute net long-term capital gains realized in any
year to the extent that a capital loss is carried forward from prior year
against such gain. To the extent such excess was retained and not exhausted by
the carryforward of prior years' capital losses, it would be subject to Federal
income tax in the hands of the Fund. Each shareholder would be treated for
Federal income tax purposes as if the Fund had distributed to him on the last
day of its taxable year his pro rata share of such excess, and he had paid his
pro rata share of the taxes paid by the Fund and reinvested the remainder in the
Fund. Accordingly, each shareholder would (a) include his pro rata share of such
excess as long-term capital gain income in his tax return for his taxable year
in which the last day of the Fund's taxable year falls, (b) be entitled either
to a tax credit on his return for, or to a refund of, his pro rata share of the
taxes paid by the Fund, and (c) be entitled to increase the adjusted tax basis
for his shares in the Fund by the difference between his pro rata share of this
excess and his pro rata share of such taxes.
     
     The percentage of Fund income that is tax-exempt is applied uniformly
to all distributions made during each calendar year to determine the percentage
of distributions to shareholders which will be treated as exempt-interest
dividends. As a result, the percentage of distributions designated as
exempt-interest dividends on shares held for less than a full calendar year may
differ from the percentage of the Fund's income which is tax-exempt during the
period for which the distributions are received. However, because the Fund
invests primarily in tax-exempt bonds, the percentage of its income which is
tax-exempt for the calendar year will generally be substantially the same as the
tax-exempt portion of income actually earned during any distribution period.
Shareholders are required to report their receipt of tax-exempt distributions
under the Code.

     Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Fund will not be deductible for Federal income tax purposes to the
extent it is deemed related to the Fund's exempt-interest dividends. Moreover,
pursuant to published guidelines, the Internal Revenue Service may deem
indebtedness to have been incurred for the purpose of acquiring or carrying
shares of the Fund even though the borrowed funds may not be directly traceable
to the purchase of shares.

     Shares of the Fund may not be an appropriate investment for persons who
are "substantial users" of facilities financed by private activity bonds and
industrial development bonds or persons related to such "substantial users."
Such persons should consult their tax advisers before investing in shares of the
Fund.

     For Federal income tax purposes, the Fund is permitted to carry forward
a net capital loss in any year to offset net capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such losses, they would not result in Federal income tax
liability to the Fund and, as noted above, would not be distributed to
shareholders. The Fund has $2,374,664 of capital loss carryforward available to
the extent provided by regulations, to offset future net realized capital gains.
The carryforward expires December 31, 2002.

     Limitations imposed by the Code on regulated investment companies like
the Fund may restrict the Fund's ability to enter into futures and options
transactions. The options and futures transactions undertaken by the Fund may
cause the Fund to recognize taxable capital gains or losses from marking to
market even though its positions have not been sold or terminated and affect the
character as long-term or short-term, and timing, of some capital gains and

<PAGE>   195
losses realized by the Fund. Also, some of the Fund's losses on its transactions
involving options and futures contracts and/or offsetting portfolio positions
may be deferred rather than being taken into account currently in calculating
the Fund's taxable income. The tax provisions applicable to these transactions,
including these mark to market, recharacterization, and loss deferral rules, may
affect the amount, timing and character of the Fund's distributions to
shareholders. Some of the applicable tax rules may be modified if the Fund is
eligible and chooses to make one or more of certain tax elections that may be
available. The Fund will take into account the special tax rules (including
consideration of available elections) applicable to options and futures
contracts in order to minimize any potential adverse tax consequences.

     The foregoing discussion relates solely to U.S. Federal income tax law
as applicable to U.S. persons (i.e., U.S. citizens or residents and U.S.
domestic corporations, partnerships, trusts or estates) subject to tax under
this law. The discussion does not address special tax rules applicable to
certain classes of investors, such as tax-exempt entities, insurance companies
and financial institutions.. Dividends, capital gain distributions, and
ownership of or gains realized on the redemption (including an exchange) of Fund
shares may also be subject to state and local taxes. A state income (and
possibly local income and/or intangible property) tax exemption is generally
available to the extent the Fund's distributions are derived from interest on
(or, in the case of intangibles taxes, the value of its assets is attributable
to) certain U.S. Government obligations and/or tax-exempt municipal obligations
issued by or on behalf of the particular state or a political subdivision
thereof, provided in some states that certain thresholds for holdings of such
obligations and/or reporting requirements are satisfied. Shareholders should
consult their own tax advisors as to the Federal, state or local tax
consequences of ownership of shares of, and receipt of distributions from, the
Fund in their particular circumstances.

     Non-U.S. investors not engaged in a U.S. trade or business with which
their Fund investment is effectively connected will be subject to U.S. Federal
income tax treatment that is different from that described above. These
investors may be subject to non-resident alien withholding tax at the rate of
30% (or a lower rate under an applicable tax treaty) on amounts treated as
ordinary dividends from the Fund and, unless an effective IRS Form W-8 or
authorized substitute is on file, to 31% backup withholding on certain other
payments from the Fund. Non-U.S. investors should consult their tax advisers
regarding such treatment and the application of foreign taxes to an investment
in the Fund.
     The Fund is not subject to Massachusetts corporate franchise or
corporate excise taxes. Provided that the Fund qualifies as a regulated
investment company under the Code, it will also not be required to pay any
Massachusetts income tax.


CALCULATION OF PERFORMANCE

     For the 30-day period ended December 31, 1994, the Fund's annualized
yield was 5.43% for Class A and 4.97% for Class B, respectively. The average
annual total return of the Class A shares of the Fund for the 1, 5 and 10 years
ended December 31, 1994 was (10.14)%, 5.29%, and 8.73%, respectively. The
cumulative total return since inception of Class B shares of the Fund was
(10.92)% as of December 31, 1994.

     The Fund's yield is computed by dividing net investment income per
share determined for a 30-day period by the maximum offering price per share
(which includes the full sales charge) on the last day of the period, according
to the following standard formula:

                                _               _
                               |  a - b      6   |
                   Yield = 2   | (_____  + 1) -1 |
                               |_   cd          _|
                                 
Where:

a = dividends and interest earned during the period.
b = net expenses accrued during the period.
c = the average daily number of fund shares outstanding during the period that
<PAGE>   196

    would be entitled to receive dividends.
d = the maximum offering price per share on the last day of the period (NAV
    where applicable).

     The Fund may advertise a tax-equivalent yield, which is computed by
dividing that portion of the yield of the Fund which is Tax-Exempt by one minus
a stated income tax rate and adding the product to that portion, if any, of the
yield of the Fund that is not Tax-Exempt. John Hancock Tax-Exempt Income Fund's
tax equivalent yield at a 31% and 36% tax rate for the 30 day period ended
December 31, 1994 was 7.87% and 8.48% for Class A shares and 7.20% and 7.77% for
Class B shares.

     The Fund's total return is computed by finding the average annual
compounded rate of return over the 1 year, 5 year and 10 year periods that would
equate the initial amount invested to the ending redeemable value according to
the following formula:


                ____________________
             n /           
              /            -1
        T =  V     ERV / P 

Where:

P   = a hypothetical initial investment of $1,000.
T   = average annual total return.
n   = number of years.

ERV = ending redeemable value of a hypothetical $1,000 investment made at the
      beginning of the 1 year, 5 year and life-of-fund periods.

     In the case of Class A shares or Class B shares, this calculation
assumes the maximum sales charge is included in the initial investment or the
CDSC is applied at the end of the period. This calculation also assumes that all
dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period. The "distribution rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.

     In addition to average annual total returns, the Fund may quote
unaveraged or cumulative total returns reflecting the simple change in value of
an investment over a stated period. Cumulative total returns may be quoted as a
percentage or as a dollar amount, and may be calculated for a single investment,
a series of investments, and/or a series of redemptions, over any time period.
Total returns may be quoted with or without taking the Fund's 4.50% sales charge
on Class A shares or the 5.00% CDSC on Class B shares into account. Excluding
the Fund's sales charge on Class A shares and the CDSC on Class B shares from a
total return calculation produces a higher total return figure.

     From time to time, in reports and promotional literature, the Fund's
yield and total return will be compared to indices of mutual funds and bank
deposit vehicles such as Lipper Analytical Services, Inc.'s "Lipper - Fixed
Income Fund Performance Analysis," a monthly publication which tracks net
assets, total return, and yield on approximately 1,700 fixed income mutual funds
in the United States. Ibottson and Associates, CDA Weisenberger and F.C. Towers
are also used for comparison purposes, as well as the Russell and Wilshire
Indices.

     Performance rankings and ratings reported periodically in national
financial publications such as MONEY Magazine, FORBES, BUSINESS WEEK, THE WALL
STREET JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S and BARRON'S, etc. will
also be utilized.

     The performance of the Fund is not fixed or guaranteed. Performance
quotations should not be considered to be representations of performance of the
Fund for any period in the future. The performance of the Fund is a function of
many factors including its earnings, expenses and number of outstanding shares.
Fluctuating market conditions; purchases, sales and maturities of portfolio
securities; sales and redemptions of shares of beneficial interest; and changes
in operating expenses are all examples of items that can increase or decrease

<PAGE>   197
the Fund's performance.


BROKERAGE ALLOCATION

     Decisions concerning the purchase and sale of portfolio securities and
the allocation of brokerage commissions are made by the Adviser pursuant to
recommendations made by its investment committee, which consists of officers and
directors of the Adviser and affiliates and officers and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner which, in the opinion of the Adviser, will offer the best
price and market for the execution of each such transaction. Purchases from
underwriters of portfolio securities may include a commission or commissions
paid by the issuer and transactions with dealers serving as market makers
reflect a "spread." Investments in debt securities are generally traded on a net
basis through dealers acting for their own account as principals and not as
brokers; no brokerage commissions are payable on such transactions.

     The Fund's primary policy is to execute all purchases and sales of
portfolio instruments at the most favorable prices consistent with best
execution, considering all of the costs of the transaction including brokerage
commissions. This policy governs the selection of brokers and dealers and the
market in which a transaction is executed. Consistent with the foregoing primary
policy, the Rules of Fair Practice of the National Association of Securities
Dealers, Inc. and other policies that the Trustees may determine, the Adviser
may consider sales of shares of the Fund as a factor in the selection of
broker-dealers to execute the Fund's portfolio transactions.

     To the extent consistent with the foregoing, the Fund will be governed
in the selection of brokers and dealers, and the negotiation of brokerage
commission rates and dealer spreads, by the reliability and quality of the
services, including primarily the availability and value of research information
and to a lesser extent statistical assistance furnished to the Adviser of the
Fund, and their value and expected contribution to the performance of the Fund.
It is not possible to place a dollar value on information and services to be
received from brokers and dealers, since it is only supplementary to the
research efforts of the Adviser. The receipt of research information is not
expected to reduce significantly the expenses of the Adviser. The research
information and statistical assistance furnished by brokers and dealers may
benefit the Life Insurance Company or other advisory clients of the Adviser,
and, conversely, brokerage commissions and spreads paid by other advisory
clients of the Adviser may result in research information and statistical
assistance beneficial to the Fund. The Fund will make no commitments to allocate
portfolio transactions upon any prescribed basis. While the Fund's officers will
be primarily responsible for the allocation of the Fund's brokerage business,
their policies and practices in this regard must be consistent with the
foregoing and will at all times be subject to review by the Trustees. For the
years ended on December 31, 1993 and 1992, no negotiated brokerage commissions
were paid on portfolio transactions. For 1994, negotiated brokerage commissions
were $28,975.

     As permitted by Section 28(e) of the Securities Exchange Act of 1934,
the Fund may pay to a broker which provides brokerage and research services to
the Fund an amount of disclosed commission in excess of the commission which
another broker would have charged for effecting that transaction. This practice
is subject to a good faith determination by the Trustees that the price is
reasonable in light of the services provided and to policies that the Trustees
may adopt from time to time. During the fiscal year ended December 31, 1994, the
Fund did not pay commissions as compensation to any brokers for research
services such as industry, economic and company reviews and evaluations of
securities.

     The Adviser's indirect parent, the Life Insurance Company, is the
indirect sole shareholder of John Hancock Freedom Securities Corporation and its
subsidiaries, three of which, Tucker Anthony Incorporated ("Tucker Anthony")
John Hancock Distributors, Inc. ("Distributors") and Sutro & Company, Inc.
("Sutro"), are broker-dealers ("Affiliated Brokers"). Pursuant to procedures
determined by the Trustees and consistent with the above policy of obtaining
best net results, the Fund may execute portfolio transactions with or through
Affiliated Brokers. During the year ended December 31, 1994, the Fund did not
execute any portfolio transactions with Affiliated Brokers.
<PAGE>   198

     Any of the Affiliated Brokers may act as broker for the Fund on
exchange transactions, subject, however, to the general policy of the Fund set
forth above and the procedures adopted by the Trustees pursuant to the
Investment Company Act. Commissions paid to an Affiliated Broker must be at
least as favorable as those which the Trustees believe to be contemporaneously
charged by other brokers in connection with comparable transactions involving
similar securities being purchased or sold. A transaction would not be placed
with an Affiliated Broker if the Fund would have to pay a commission rate less
favorable than the Affiliated Broker's contemporaneous charges for comparable
transactions for its other most favored, but unaffiliated, customers, except for
accounts for which the Affiliated Broker acts as clearing broker for another
brokerage firm, and any customers of the Affiliated Broker not comparable to the
Fund as determined by a majority of the Trustees who are not interested persons
(as defined in the Investment Company Act) of the Fund, the Adviser or the
Affiliated Brokers. Because the Adviser, which is affiliated with the Affiliated
Brokers, has, as an investment adviser to the Fund, the obligation to provide
investment management services, which includes elements of research and related
investment skills, such research and related skills will not be used by the
Affiliated Brokers as a basis for negotiating commissions at a rate higher than
that determined in accordance with the above criteria. The Fund will not effect
principal transactions with Affiliated Brokers.


TRANSFER AGENT SERVICES

     John Hancock Investor Services Corporation. ("Investor Services"), P.O.
Box 9116, Boston, MA 02205-9116, a wholly owned indirect subsidiary of the Life
Insurance Company, is the transfer and dividend paying agent for the Fund. The
Fund pays Investor Services an annual fee for Class A of $19.00 per shareholder
account and for Class B shares $21.50, plus certain out-of-pocket expenses.


CUSTODY OF PORTFOLIO

     Portfolio securities of the Fund are held pursuant to a custodian
agreement between the Fund and Investors Bank & Trust Company, 24 Federal
Street, Boston, Massachusetts 02110. Under the custodian agreement, Investors
Bank & Trust performs custody, portfolio and Fund accounting services.


     INDEPENDENT AUDITORS The independent auditors of the Fund are Ernst &
Young LLP, 200 Clarendon Street, Boston, Massachusetts 02116. Ernst & Young
audits and renders an opinion of the Fund's annual financial statements and
prepares the Fund's annual Federal income tax return.

                                   APPENDIX A

                            TAX EXEMPT BOND RATINGS

     Below is a description of the six ratings that may apply to the Fund's
investments in Tax-Exempt Bonds.

TAX-EXEMPT BOND RATINGS

     Moody's describes its six highest ratings for Tax-Exempt Bonds as
follows:

     Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
'gilt edge'. Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

     Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long term risks appear somewhat larger than in Aaa securities.

     Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment some time in the future.

     Bonds which are rated Baa are considered as medium grade obligations;
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

     Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

     Bonds which are rated B generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

     The six highest ratings of Standard & Poor's for Tax-Exempt Bonds are
AAA (Prime), AA (High Grade), A (Good Grade), BBB (Medium Grade), BB and B:

     AAA       This is the highest rating assigned by Standard & Poor's to a
               debt obligation and indicates an extremely strong capacity to
               pay principal and interest.

     AA        Bonds rated AA also qualify as high-quality debt obligations.
               Capacity to pay principal and interest is very strong, and in
               the majority of instances they differ from AAA issues only in
               small degree.
     
     A         Bonds rated A have a strong capacity to pay principal and   
               interest, although they are somewhat more susceptible to the
               adverse effects of changes in circumstances and economic
               conditions.

     BBB       Bonds rated BBB are regarded as having an adequate capacity to
               pay principal and interest. Whereas they normally exhibit
               protection parameters, adverse economic conditions or changing
               circumstances are more likely to lead to a weakened capacity
               to pay principal and interest for bonds in this category than    
               for bonds in the A category.

<PAGE>   200

     BB        Debt rated BB has less near-term vulnerability to default than
               other speculative issues. However, it faces major ongoing
               uncertainties or exposure to adverse business, financial, or
               economic conditions which could lead to inadequate capacity to
               meet timely interest and principal payments. The BB rating
               category is also used for debt subordinated to senior debt
               that is assigned an actual or implied BBB- rating.

     B         Debt rated B has a greater vulnerability to default but
               currently has the capacity to meet interest payments and
               principal repayments. Adverse business, financial, or economic
               conditions will likely impair capacity or willingness to pay
               interest and repay principal. The B rating category is also
               used for debt subordinated to senior debt that is assigned an
               actual or implied BB or BB- rating.


Fitch describes its ratings for Tax-Exempt Bonds as follows:

     AAA       Bonds considered to be investment grade and of the highest
               credit quality. The obligor has an exceptionally strong
               ability to pay interest and repay principal, which is unlikely
               to be affected by reasonably foreseeable events.

     AA        Bonds considered to be investment grade and of very high
               credit quality. The obligor's ability to pay interest and
               repay principal is very strong, although not quite as strong
               as bonds rated "AAA". Because bonds rated in the "AAA" and
               "AA" categories are not significantly vulnerable to foresee
               uture developments, short-term debt of these issuers is
               generally rated F-1+.

     A         Bonds considered to be investment grade and of high credit
               quality. The obligor's ability to pay interest and repay
               principal is considered strong, but may be more vulnerable to
               adverse changes in economic conditions and circumstances than
               bonds with higher ratings.

     BBB       Bonds considered to be investment grade and of satisfactory
               credit quality. The obligor's ability to pay interest and
               repay principal is considered to be adequate. Adverse changes
               in economic conditions and circumstances, however, are more
               likely to have adverse impact on these bonds and, therefore,
               impair timely payment. The likelihood that the ratings of
               these bonds will fall below investment grade is higher than
               for bonds with higher ratings.

     BB        Bonds are considered speculative. The obligor's ability to pay
               interest and repay principal may be affected over time by
               adverse economic changes. However, business and financial
               alternatives can be identified that could assist the obligor
               in satisfying its debt service requirements.

     B         Bonds are considered highly speculative. While bonds in this
               class are currently meeting debt service requirements, the
               probability of continued timely payment of principal and
               interest reflects the obligor's limited margin of safety and
               the need for reasonable business and economic activity
               throughout the life of the issue.

     Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade (MIG). This distinction is in
recognition of the differences between short-term credit risk and long-term
risk. Factors affecting the liquidity of the borrower are uppermost in
importance in short-term borrowing, while various factors of the first
importance in bond risk are of lesser importance in the short-term run. Symbols
used will be as follows:

     MIG 1 Loans bearing this designation are of the best quality, enjoying
     strong protection from established cash flows of funds for their
     servicing or from established and broad-based access to the market for
     refinancing, or both.

<PAGE>   201

     MIG 2 Loans bearing this designation are of high quality, with margins
     of protection ample although not so large as in the preceding group.

     MIG 3 Loans bearing this designation are of favorable quality, with all
     securities elements accounted for but lacking the undeniable strength
     of the preceding grades. Market access for refinancing, in particular,
     is likely to be less well established.

     Standard & Poor's ratings for state and municipal notes and other
short-term loans are designated Standard & Poor's Grade (SP).

     SP-1 Very strong or strong capacity to pay principal and interest.
     Those issues determined to possess overwhelming safety characteristics
     will be given a plus (+) designation.

     SP-2 Satisfactory capacity to pay principal and interest.

     SP-3 Speculative capacity to pay principal and interest.

     Fitch Ratings for short-term debt obligations that are payable on
demand or have original maturities of up to three years including commercial
paper, certificates of deposits, medium term notes and municipal and investment
notes are designated by the following ratings:

     F-1+      Exceptionally Strong Credit Quality. Issues assigned this
     rating are regarded as having the strongest degree of assurance for
     timely payment.

     F-1 Very Strong Credit Quality. Issues assigned this rating reflect an
     assurance of timely payment only slightly less in degree than issues
     rated F-1+.

     F-2 Good Credit Quality. Issues assigned this rating have a
     satisfactory degree of assurance for timely payment, but the margin for
     safety is not as great as for issues assigned F-1+ and F-1 ratings.

     F-S Weak Credit Quality. Issues assigned this rating have
     characteristics suggesting a minimal degree of assurance for timely
     payment and are vulnerable to near-term adverse changes in financial
     and economic conditions.

                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

[A 1 1/4" x 1" photo of Edward J. Boudreau Jr., Chairman and Chief Executive
Officer, flush right, next to second paragraph.]

The stock market's record-breaking, whirlwind performance in 1995 will be a
tough act to follow in 1996. In fact, we've already seen greater market
volatility this year, particularly among last year's leaders -- technology
stocks. That's to be expected after a year that saw market indexes soar,
including the Standard & Poor's 500-Stock Index's 37% advance. While many of the
same economic conditions that fostered the stellar 1995 market are still in
place -- slow economic growth, muted inflation and decent corporate earnings --
it would be unrealistic to expect the market to stage a repeat in 1996. The old
saying "trees don't grow to the sky" comes to mind. Shareholders would do well
to temper expectations of investment returns and perhaps revisit their
investment allocations with their financial advisor to determine if rebalancing
their portfolio makes sense.

   No matter how you scale back your market expectations, you should always be
able to count on consistent customer service performance. At John Hancock Funds,
we never stop working to find ways to sustain and improve the quality of
information and the level of assistance we provide you. Our commitment to this
task is no less than John Hancock's loyalty was to his fledgling country when he
is said to have uttered, "if it does the public good, burn Boston." We won't go
that far, of course, but we share our namesake's dedication to putting the
public before all else.

   In our case, that public is you, our shareholders. We take very seriously the
role you have entrusted to us, that of helping you achieve your financial goals.
Part of that will always involve good customer service. So please do not
hesitate to call your Customer Service Representative at 1-800-225-5291 if you
have any questions or need information. We take pride in helping you with the
same spirit that John Hancock displayed at the dawning of America.

Sincerely,


/s/ Edward J. Boudreau, Jr.

             MUNICIPAL BONDS ENJOY STRONGEST YEAR IN NEARLY A DECADE

Municipal bonds enjoyed an impressive comeback in 1995, posting some of their
best returns in nearly a decade. From the very outset of the year, all bond
markets, including the municipal market, rallied on news that the economy's rate
of growth was slowing and inflation was subdued. The year-long rally was
beneficial to municipal bonds -- particularly in the first quarter, when they
rated as the top fixed-income category during that period.

   However, by spring the municipal bond market stalled as talk of tax reform
took center stage. Investors worried that various proposals -- particularly the
flat-tax proposal -- might affect the attractiveness of municipals if enacted.
That political rhetoric caused municipals to underperform Treasury bonds in the
second quarter. While we and many other market participants believe that the
flat tax doesn't stand much of a chance of being enacted before 1998, if ever,
the market nonetheless used the topic as an excuse to consolidate.

"Thomas C. Goggins, Portfolio Manager".]

   By the second half of the year, municipals -- which were priced attractively
relative to taxable bonds at the time -- began to move up again as supply waned
and demand strengthened. Two interest-rate cuts by the Federal Reserve Board
gave the muni market an added boost. All in all, municipal bond funds enjoyed
their strongest performance since 1986.

   The municipal bond market's strong performance was reflected in John Hancock 
Tax-Exempt Income Fund's performance. For the 12 months ended December 31, 1995,
the Fund's Class A and Class B shares posted total returns of 16.60% and 15.70%,
respectively, at net asset value. Those returns compared to

STRATEGIC CHANGES

Due to several portfolio changes we made over the past six months, the Fund's
performance gained ground on our competitors throughout the year and ended the
period matching its peers. First, we focused on adding more discount bonds.
During periods of falling interest rates, discount bonds -- which sell below
their par (face) value -- generally appreciate more than par bonds, and more
than premium bonds that sell above par value.

   Second, we worked steadily all year to improve the call protection of the
Fund. We did that by adding more non-callable bonds, which can't be redeemed by
their issuer before their scheduled maturity date. Non-callable bonds offer the
advantages of a predictable stream of income and the ability to outperform the
market. What's more, because they are relatively scarce, non-callables tend to
be more easily traded, or liquid.

driving it." The first listing is "Wayne County/Northwest Airlines" followed by
an up arrow and the phrase "Improving profitability for airline". The second

"Growth in revenues and earnings". The third listing is "Housing bonds" followed
by a flat arrow and the phrase "Rising risk of prepayments". Footnote below
reads: "See "Schedule of Investments." Investment holdings are subject to
change.]

   Finally, we actively managed the Fund's duration, which measures how
sensitive its share price is to changes in interest rates. The longer a fund's
duration, the more its share price will rise when interest rates are falling and
fall when interest rates are rising. At the beginning of the year, the Fund's
duration was relatively long, which helped its performance in the first quarter
of the year. But by the end of June, we had shortened our duration in response
to the spring's more volatile market. We reversed course and lengthened our
duration again in mid-summer because we felt that interest rates would continue
to decline. That strategy ultimately benefited the Fund when the Federal Reserve
made two interest rate cuts in the second half of the year.

FOCUS ON SECTORS

While we kept the Fund's stake in health-care bonds steady at about 13% of
investments, we made some changes among those holdings. Heightened competition
and proposed cuts in Medicare and Medicaid have made the fate of many hospitals
and health-care organizations much less certain. As a result, we sold some of
what we believed to be the more vulnerable holdings and concentrated on
individual hospitals that we believe will be able to withstand, and even benefit
from, a more competitive environment.

   We used some of the proceeds to purchase industrial revenue bonds, a sector
that generally performed well during the period. Bonds issued by the city of
Walla Walla, Washington for

a Scott Paper facility that recycles paper into liner board did well on the
improving fundamentals of the paper industry. During the past six months we also
added some airline bonds including those issued by Wayne County, Michigan for
Northwest Airlines, which will fund the remodeling of the airline's terminal at
Detroit's Metropolitan Airport. Another addition was on airline bond issued by
Indianapolis, Indiana for a United Airlines maintenance facility. These bonds
also performed well as a result of increased profitability in the airline
sector.

   Not all sectors of the municipal market participated equally in the rally. 
Housing bonds were generally laggards throughout 1995. These bonds typically
underperform other sectors when the market is rising, because there is some
concern that they will be paid off before their scheduled maturity dates.
However, we held onto them because they are generally high-quality bonds which
offer relatively high yields.

OUTLOOK

   Political haggling over various tax-reform proposals could continue to draw
headlines in 1996. If that is the case, the municipal bond market could
experience further volatility in the months to come. Our view is that it's
unlikely that any significant tax reform will be enacted within the next two
years. And we're not even convinced that the flat tax is viable. So we think the
market has overreacted.

   We believe that the tax-reform scare has actually created an opportunity. At
the end of 1995, municipals were priced attractively compared to Treasuries. In
fact, there was only one other time in recent history that municipals were this
cheap relative to Treasuries. In our experience, it is in times like these that
municipals offer good value for investors seeking after-tax income.

   It may be difficult for municipals to achieve the same exceptional gains they
made in 1995. However, there are several reasons why we're optimistic about
1996. We believe that economic growth will continue to slow, inflation will
remain subdued and, as a result, interest rates can continue to fall this year.
Since bond prices generally move in the opposite direction of interest rates,
that could be good news for bonds. What's more, the supply of new municipals
issued should remain relatively weak. And if demand stays constant or improves,
that too could be a positive.

total returns for the John Hancock Tax-Exempt Income Fund. Total return is a
performance measure that equals the sum of all dividends and capital gains,
assuming reinvestment of these distributions and the change in the price of the
Fund's average net assets. Performance figures include the maximum applicable
sales charge of 4.50% for Class A shares. The effect of the maximum contingent
deferred sales charge for Class B shares (maximum 5% and declining to 0% over
six years) is included in Class B performance. Performance is affected by a
12b-1 plan, which commenced on March 24, 1987 and January 3, 1994 for both Class
A and Class B shares, respectively. Remember that all figures represent past
performance and are no guarantee of how the Fund will perform in the future.
Also, keep in mind that the total return and share price of the Fund's
investments will fluctuate. As a result, your Fund's shares may be worth more or
less than their original cost, depending on when you sell them.


Note: A portion of the Fund's income may be subject to taxes. Some investors may
be subject to the Alternative Minimum Tax. Capital gains are taxable.

The charts on the right show how much a $10,000 investment in the John Hancock
Tax-Exempt Income Fund would be worth on December 31, 1995, assuming you have
been invested for the past ten years or since the day each class of shares
started and reinvested all distributions. For comparison, we've shown the same
$10,000 investment in the Lehman Brothers Municipal Bond Index -- an unmanaged
index that includes approximately 15,000 bonds and is commonly used as a measure
of bond performance.

                   John Hancock Funds - Tax-Exempt Income Fund

NOTE A --
ACCOUNTING POLICIES

John Hancock Tax-Exempt Income Fund (the "Fund") is a diversified open-end
investment management company registered under the Investment Company Act of
1940. The investment objective of the Fund is to provide as high a level of
dividend income exempt from Federal income tax as is consistent with
preservation of capital and the Fund's requirements for liquidity.

   The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, dividends and liquidation, except that certain expenses,
subject to the approval of the Trustees, may be applied differently to each
class of shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a class
which bears distribution/service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan. Class A
shares are subject to an initial sales charge of up to 4.50% and a 12b-1
distribution plan. Class B shares are subject to a contingent deferred sales
charge and a separate 12b-1 distribution plan. Significant accounting policies
of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or, at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly-owned subsidiary of The Berkeley Financial Group,
may participate in a joint repurchase agreement transaction. Aggregate cash
balances are invested in one or more repurchase agreements, whose underlying
securities are obligations of the U.S. government and/or its agencies. The
Fund's custodian bank receives delivery of the underlying securities for the
joint account on the Fund's behalf. The Adviser is responsible for ensuring that
the agreement is fully collateralized at all times.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. At the time the Fund enters into a financial futures
contract, it will be required to deposit with its custodian a specified amount
of cash or U.S. government securities, known as "initial margin", equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract will be valued at the official settlement price
of the board of trade or U.S. commodities exchange. Subsequent payments, known
as "variation margin", to and from the broker will be made on a daily basis as
the market price of the financial futures contract fluctuates. Daily variation
margin adjustments, arising from this "mark to market", will be recorded by the
Fund as unrealized gains or losses.

   When the contracts are closed, the Fund will recognize a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening, or realizing the benefits of closing
out, futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

   For Federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

   At December 31, 1995, open positions in financial futures contracts were as
follows:

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $8,110,320 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. If such carryforwards are used by the Fund,
no capital gain distributions will be made. The carryforwards expire as follows:
December 31, 2002 -- $2,374,664 and December 31, 2003 -- $5,735,656.

DIVIDENDS, DISTRIBUTIONS, AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

   The Fund records all distributions to shareholders from net investment income
and realized gains on the ex-dividend date. Such distributions are determined in
conformity with income tax regulations, which may differ from generally accepted
accounting principles. Dividends paid by the Fund, if any, with respect to each
class of shares will be calculated in the same manner, at the same time and will
be in the same amount, except for the effect of expenses that may be applied
differently to each class as explained previously. 

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution/service fees, if any, are calculated daily at the class level based
on the appropriate net assets of each class and the specific expense rate(s)
applicable of each class.

NOTE B --
MANAGEMENT FEE AND TRANSACTIONS WITH AFFILIATES AND OTHERS 

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of: (a) 0.55% of the first $500,000,000 of the
Fund's average daily net asset value, (b) 0.50% of the next $500,000,000, and
(c) 0.45% of the Fund's average daily net asset value in excess of
$1,000,000,000.

   In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares, the fee payable to the
Adviser will be reduced to the extent of such excess, and the Adviser will make
additional arrangements necessary to eliminate any remaining excess expenses.
The current limits are 2.5% of the first $30,000,000 of the Fund's average daily
net asset value, 2.0% of the next $70,000,000, and 1.5% of the remaining average
daily net asset value. $76,644 of custodian fees have been reduced by balance
credits applied during the period ended December 31, 1995.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly-owned subsidiary of the Adviser. For the period ended December
31, 1995, JH Funds received net sales charges on sales of Class A shares of the
Fund in the amount of $779,270. Out of this amount, $90,638 was retained and
used for printing prospectuses, advertising, sales literature and other
purposes, $52,648 was paid as sales commissions and service fees to unrelated
broker-dealers and $635,984 was paid as sales commissions and service fees to
sales personnel of John Hancock Distributors, Inc. ("Distributors"), Tucker
Anthony, Incorporated ("Tucker Anthony") and Sutro & Co., Inc. ("Sutro"). The
Adviser's indirect parent, John Hancock Mutual Life Insurance Company, is the
indirect sole shareholder of Distributors and John Hancock Freedom Securities
Corporation and its subsidiaries, which include Tucker Anthony and Sutro, all of
which are broker-dealers.

   Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value 

                                       22

                   John Hancock Funds - Tax-Exempt Income Fund

at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from CDSC are paid to JH Funds and are used in whole or in
part to defray its expenses related to providing distribution related services
to the Fund in connection with the sale of Class B shares. For the period ended
December 31, 1995, contingent deferred sales charges received by JH Funds
amounted to $16,759.

   In addition, to compensate JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A and Class B shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B average daily net
assets to reimburse JH Funds for its distribution and service costs. Up to a
maximum of 0.25% of these payments may be service fees as defined by the amended
Rules of Fair Practice of the National Association of Securities Dealers. Under
the amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

   The Fund has a transfer agent agreement with John Hancock Investor Services
Corporation ("Investor Services"), a wholly-owned subsidiary of The Berkeley
Financial Group. Prior to October 1, 1995, the Fund paid transfer agent fees as
a class specific expense based on the number of shareholder accounts and certain
out-of-pocket expenses. For the nine months ended September 30, 1995 the
transfer expense, calculated as a class specific expense, was $567,657 for Class
A and $12,261 for Class B, respectively. Effective October 1, 1995, transfer
agent expense is a fund expense.

   Messrs. Edward J. Boudreau, Jr. and Richard S. Scipione are directors and/or
officers of the Adviser, and/or its affiliates as well as Trustees of the Fund.
The compensation of unaffiliated Trustees is borne by the Fund. Effective with
the fees paid for 1995, the unaffiliated Trustees may elect to defer for tax
purposes their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock Funds, as applicable, to cover its liability with regard to the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability is marked to market on a periodic basis and income earned by the
investment is recorded on the Fund's books.

NOTE C -- 
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term securities, during the period
ended December 31, 1995, aggregated $644,316,886 and $638,779,810, respectively.
Purchases and proceeds from sales of short-term municipal obligations during the
period ended December 31, 1995, aggregated $6,500,000 and $8,500,000,
respectively. There were no purchases or sales of long-term obligations of the
U.S. government and its agencies during the period ended December 31, 1995.

   The cost of investments owned at December 31, 1995 for Federal income tax
purposes was $474,106,074. Gross unrealized appreciation and depreciation of
investments aggregated $42,833,371 and $8,525, respectively, resulting in net
unrealized appreciation of $42,824,846.

NOTE D --
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended December 31, 1995, the Fund has reclassified amounts to
reflect increases in accumulated net investment income and accumulated realized
loss on investments of $87,923. This represents the cumulative amounts necessary
to report these balances on a tax basis, excluding certain temporary
differences, as of December 31, 1995. Additional adjustments may be needed in
subsequent reporting periods. These reclassifications, which have no impact on
the net asset value of the Fund, are primarily attributable to certain
differences in the computation of distributable income and capital gains under
federal tax rules versus generally accepted accounting principles.

NOTE E --
PLAN OF REORGANIZATION

On December 11, 1995, the Board of Trustees of the Fund approved a plan of
reorganization between the Fund and the John Hancock Tax-Free Bond Fund ("Bond
Fund") providing for the transfer of substantially all of the assets and
liabilities of the Fund to the Bond Fund in exchange solely for Class A and
Class B shares of the Bond Fund to be distributed to the Fund's Class A and
Class B shareholders, respectively.

REPORT OF ERNST & YOUNG LLP, 
INDEPENDENT AUDITORS 

To the Trustees and Shareholders of 
John Hancock Tax-Exempt Income Fund

We have audited the accompanying statement of assets and liabilities of John
Hancock Tax-Exempt Income Fund (the "Fund"), including the schedule of
investments, as of December 31, 1995, and the related statement of operations
for the year then ended, the statement of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
periods indicated therein. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1995, by correspondence with the custodian and brokers, or other
appropriate auditing procedures when replies from brokers were not received. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of John
Hancock Tax-Exempt Income Fund at December 31, 1995, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the indicated periods, in conformity with generally accepted accounting
principles.

                   NOTES TO PRO FORMA FINANCIAL STATEMENTS -
                                  (UNAUDITED)
                               DECEMBER 31, 1995


Pro forma information is intended to provide shareholders of John Hancock Tax
Exempt Income Fund (TEIF) with information about the impact of the proposed
merger by indicating how the merger might have affected information had the
merger been consummated as of January 1, 1995

The unaudited pro forma combined statements of assets and liabilities and
results of operations as of December 31, 1995, have been prepared to reflect
the merger of John Hancock Tax Free Bond (TFB) and TEIF after giving effect to
pro forma adjustments described in the notes listed below.

(a) Acquisition by TFB of all of the net assets of TEIF and issuance
    of TFB Class A and Class B shares in exchange for all of the outstanding
    Class A and Class B shares, respectively of TEIF.

(b) The investment advisory fee was adjusted to reflect the application
    of the fee structure currently applicable to Tax Exempt Income Fund which
    will be adopted for TFB after the reorganization: 0.55% of the first
    $500,000,000 of the Fund's average daily net assets, 0.50% of the next
    $500,000,000 and 0.45% of the Fund's average daily net assets in excess of 
    $1,000,000,000.

(c) The 12b-1 fee was adjusted to reflect the application of the fee
    structure which will be proposed to the shareholders of TFB to
    increase the Fund's Class A Rule 12b-1 fee from its current rate of 
    0.15% to 0.25%. The increase will not take effect until December 23, 1996
    or later.

(d) The 12b-1 fee was adjusted to reflect the Board of Trustees of 
    TFB's approval of the termination of limiting the Class B Rule fee to
    0.90%. As a result, Class B Rule 12b-1 fee will increase to 1.00%. The
    increase will not take effect until December 23, 1996 or later.


(e) The transfer agent fee for each of the Class A and Class B shares
    is the total of the respective individual fund's transfer agent fees. 
    The main criteria in determining the transfer agent fees for a specific
    class is the number of the shareholder accounts.

(f)  The actual expenses incurred by TFB and TEIF for various expenses
    included on a pro forma basis were reduced to reflect the estimated savings
    arising from the merger.

(g) Reflects removal of the TFB's management fee expense limitation.

Ladies and Gentlemen:

In connection with the filing of a registration statement under the Securities
Act of 1933, as amended (the "Act"), on Form N-14, with respect to the shares
of beneficial interest of John Hancock Tax-Free Bond Fund, a Massachusetts
business trust (the "Fund"), it is the opinion of the undersigned that these
shares when issued will be legally issued, fully paid and nonassessable.

In connection with this opinion it should be noted that the Fund is an entity
of the type generally known as a "Massachusetts business trust." Under
Massachusetts law, shareholders of a Massachusetts business trust may be held
personally liable for the obligations of the trust. However, the Fund's
Declaration of Trust disclaims shareholder liability for obligations of the
Fund and indemnifies any shareholder of the Fund, with such indemnification to
be paid solely out of the assets of the Fund. Therefore, the shareholder's risk
is limited to circumstances in which the assets of the Fund are insufficient to
meet the obligations asserted against such assets.

The undersigned hereby consents to the filing of a copy of this opinion, as an
exhibit to the Fund's registration statement on Form N-14, with the Securities
and Exchange Commission and with the various state securities administrators.

Sincerely,

JOHN HANCOCK ADVISERS, INC.

Board of Trustees
John Hancock Tax-Free Bond Fund

Dear Members of the Boards of Trustees:

        You have requested our opinion regarding the federal income tax
consequences of the acquisition by John Hancock Tax-Free Bond Fund ("Acquiring
Fund") of all of the assets of John Hancock Tax-Exempt Income Fund ("Acquired
Fund") in exchange solely for (i) the assumption by Acquiring Fund of all of
the liabilities of Acquired Fund and (ii) the issuance of Class A and Class B
voting shares of beneficial interest of Acquiring Fund (the "Acquiring Fund
Shares") to Acquired Fund, followed by the distribution by Acquired Fund, in
liquidation of Acquired Fund, of the Acquiring Fund Shares to the shareholders
of Acquired Fund and the termination of Acquired Fund (the foregoing together
constituting the "reorganization" or the "transaction").

        In rendering this opinion, we have examined and relied upon (i) the
prospectus for the Class A and Class B shares of Acquired Fund, dated May 1,
1995, as supplemented on December 11, 1995, (ii) the statement of additional
information for the Class A and Class B shares of Acquired Fund, dated May 1,
1995, (iii) the prospectus for the Class A and Class B shares of Acquiring
Fund, dated May 1, 1995, as supplemented November 28, 1995, (iv) the statement
of additional information for the Class A and Class B shares of Acquiring Fund,
dated May 1, 1995, (v) the registration statement on Form N-14 of Acquiring
Fund relating to the

transaction (the "Registration Statement") filed with the 
Securities and Exchange Commission (the "SEC") on February ____, 1996, (vi) the
proxy statement and prospectus relating to the transaction dated March 15, 1996
(the "Proxy Statement"), (vii) the Agreement and Plan of Reorganization, made
_______________, 1996, between Acquiring Fund and Acquired Fund (the
"Agreement"), (viii) the representation letters on behalf of Acquiring Fund and
Acquired Fund referred to below and (ix) such other documents as we deemed
appropriate.  We have assumed that the parties to the Agreement have acted and
will act in accordance with the terms of the Agreement and all other documents
relating to the transaction.  

        The conclusions expressed herein represent our judgment regarding the
proper treatment of Acquiring Fund, Acquired Fund and the shareholders of
Acquired Fund on the basis of our analysis of the Internal Revenue Code of
1986, as amended (the "Code"), case law, Treasury regulations and the rulings
and other pronouncements of the Internal Revenue Service (the "Service") which
exist at the time this opinion is rendered.  Such authorities are subject to
prospective or retroactive change, and we do not undertake any responsibility
to advise you of any such change.  Our opinion represents our best judgment
regarding the issues presented and is not binding upon the Service or any
court.  Moreover, our opinion does not provide any assurance that a position
taken in reliance on such opinion will not be challenged by the Service and
does not constitute any representation or warranty that such position, if so
challenged, will not be rejected by a court.

                                    FACTS
                                    -----

        We understand the facts relating to the transaction to be as described
hereinafter.  Acquiring Fund is a business trust established under the laws of
The Commonwealth of Massachusetts in 1989 and is registered as an open-end
investment company under the Investment Company Act of 1940, as amended (the
"1940 Act").  

        The investment objective of Acquiring Fund is to obtain as high a level
of interest income exempt from federal income taxes as is consistent with
preservation of capital.  Acquiring Fund seeks to achieve its investment
objective by investing primarily in municipal bonds, notes and commercial
paper, the interest on which is exempt from federal income taxes.  Acquiring
Fund may also enter into repurchase agreements and acquire certain taxable
money market securities, as described in its prospectus.

        Acquired Fund is a business trust established under the laws of The
Commonwealth of Massachusetts in 1976 and is registered as an open-end
investment company under the 1940 Act.

        The investment objective of Acquired Fund is to provide as high a level
of dividend income exempt from federal income tax as is consistent with
preservation of capital and Acquired Fund's requirements for liquidity. 
Acquired Fund seeks to achieve its objective by investing in a diversified
portfolio of municipal bonds and other securities, the interest on which is, at
the time of issue, excludable from gross income for federal income tax purposes
in the opinion of bond counsel to the issuer.  Acquired Fund may also enter
into repurchase agreements and acquire certain other short-term, taxable
investments, as described in its prospectus.

        The steps comprising the reorganization, as set forth in the Agreement,
are as follows:

                (i)  Acquired Fund will transfer to Acquiring Fund all of its 
assets (consisting, without limitation, of portfolio securities and instruments,
dividend and interest receivables, cash and other assets).  In exchange for the
assets transferred to it, Acquiring Fund will (A) assume all of the liabilities
of Acquired Fund (comprising all of its known and unknown liabilities and
referred to hereinafter as the "Acquired Fund Liabilities") and (B) issue
Acquiring Fund Shares to Acquired Fund that have an aggregate net asset value
equal to the value of the assets transferred to Acquiring Fund by Acquired
Fund, less the value of the Acquired Fund Liabilities assumed by Acquiring
Fund.

                (ii)  Promptly after the transfer of its assets to Acquiring 
Fund, Acquired Fund will distribute in liquidation the Acquiring Fund Shares it
receives in the exchange to Acquired Fund shareholders pro rata in exchange for
their surrender of their shares of Acquired Fund ("Acquired Fund Shares").  In
these exchanges, holders of Acquired Fund Shares designated as Class A ("Class
A Acquired Fund Shares") will receive Acquiring Fund Shares designated as Class
A ("Class A Acquiring Fund Shares"), and holders of Acquired Fund Shares
designated as Class B ("Class B Acquired Fund Shares") will receive Acquiring
Fund Shares designated as Class B ("Class B Acquiring Fund Shares").

                (iii)  After such exchanges, liquidation and distribution, the
existence of Acquired Fund will be promptly terminated in accordance with
Massachusetts law.

        The Agreement and the transactions contemplated thereby were approved
by the Board of Trustees of Acquiring Fund at a meeting held on November 28,
1995.  Acquiring Fund shareholders are not required and were not asked to
approve the transaction.  The Agreement and the transactions contemplated
thereby were approved by the Board of Trustees of Acquired Fund at a meeting
held on December 11, 1995, subject to the approval of Acquired Fund
shareholders.  Acquired Fund shareholders approved the transaction at a meeting
held on May 1, 1996.

        Massachusetts law does not provide dissenters' rights for Acquired Fund
shareholders in the transaction.  Additionally, it is the position of the
Division of Investment Management of the SEC that appraisal rights, in contexts
such as the reorganization, are inconsistent with Rule 22c-1 under the 1940 Act
and are therefore preempted and invalidated by such rule.  Consequently,
Acquired Fund shareholders will not have dissenters' or appraisal rights in the
transaction.

        Our opinions set forth below are subject to the following factual
assumptions being true and correct (including statements relating to future
actions and facts represented to be to the best knowledge of management,
whether or not known).  Authorized representatives of Acquiring Fund and
Acquired Fund have represented to us by letters of even date herewith that the
following assumptions are true and correct:  

        (a)  Acquiring Fund has no plan or intention to redeem or otherwise
reacquire any of the Acquiring Fund Shares received by shareholders of Acquired
Fund in the transaction except in connection with its legal obligation under
Section 22(e) of the 1940 Act as a registered open-end investment company to
redeem its own shares.

        (b)  After the transaction, Acquiring Fund will continue the historic
business of Acquired Fund and will use all of the assets acquired from Acquired
Fund, which are Acquired Fund's historic business assets, i.e., assets not
acquired as part of or in contemplation of the transaction, in the ordinary
course of a business.
             
        (c)  Acquiring Fund has no plan or intention to sell or otherwise
dispose of any assets of Acquired Fund acquired in the transaction, except for
dispositions made in the ordinary course of its business (i.e., dispositions
resulting from investment decisions made after the reorganization on the basis
of investment considerations independent of the reorganization) or to maintain

its qualification as a regulated investment company under Subchapter M of the
Code.

        (d)  The shareholders of Acquiring Fund and the shareholders of
Acquired Fund will bear their respective expenses, if any, in connection with
the transaction.

        (e)  Acquiring Fund and Acquired Fund will each bear its own expenses
incurred in connection with the transaction.  Any liabilities of Acquired Fund
attributable to such expenses that remain unpaid on the closing date of the
transaction and are assumed by Acquiring Fund in the transaction are
attributable to Acquired Fund's expenses that are solely and directly related
to the transaction in accordance with the guidelines established in Rev. Rul.
73-54, 1973-1 C.B. 187.  

        (f)  There is no indebtedness between Acquiring Fund and Acquired Fund.

        (g)  Acquired Fund has elected to be treated as a regulated investment
company under Subchapter M of the Code, has qualified as a regulated investment
company for each taxable year since its inception, and qualifies as such for
its final taxable year ending on the closing date of the transaction.

        (h)  Acquiring Fund has elected to be treated as a regulated investment
company under Subchapter M of the Code, has qualified as a regulated investment
company for each taxable year since its inception, and qualifies as such as of
the date of the transaction.  

        (i)  Neither Acquiring Fund nor Acquired Fund is under the jurisdiction
of a court in a Title 11 or similar case within the meaning of Section
368(a)(3)(A) of the Code.

        (j)  Acquiring Fund does not own and since its inception has not owned,
directly or indirectly, any shares of Acquired Fund.

        (k)  Acquiring Fund will not pay cash in lieu of fractional shares in
connection with the transaction.
        
        (l)  As of the date of the transaction, the fair market value of the
Acquiring Fund Shares issued to Acquired Fund in exchange for the assets of
Acquired Fund is approximately equal to the fair market value of the assets of
Acquired Fund received by Acquiring Fund, minus the value of the Acquired Fund
Liabilities assumed by Acquiring Fund.

        (m)  Acquired Fund shareholders will be in control (within the meaning
of Sections 368(a)(2)(H) and 304(c) of the Code, which provide that control
means the ownership of shares possessing at least 50% of the total combined
voting power of all classes of shares that are entitled to vote or at least 50%
of the total value of shares of all classes) of Acquiring Fund after the
transaction, and to the best knowledge of management of Acquired Fund, there is
no intention on the part of any shareholders of Acquired Fund to redeem, sell,
exchange, or otherwise dispose of a number of the shares of Acquiring Fund
received in the transaction that would affect the retention of control of
Acquiring Fund by former shareholders of Acquired Fund after consummation of
the transaction.

        (n)  At the time of the transaction, Acquiring Fund does not have
outstanding any warrants, options, convertible securities, or any other type of
right pursuant to which any person could acquire shares of Acquiring Fund that,
if exercised or converted, would affect the acquisition or retention of control
(within the meaning of Sections 368(a)(2)(H) and 304(c) of the Code) of
Acquiring Fund by the shareholders of Acquired Fund.

        (o)  The principal business purposes of the transaction are to combine
the assets of Acquiring Fund and Acquired Fund in order to capitalize on
economies of scale in expenses such as the costs of accounting, legal, transfer
agency, insurance, custodial, and administrative services, to eliminate the
potential adverse effects on each fund's asset growth of competing with the
other fund, and to increase diversification.

        (p)  As of the date of the transaction, the fair market value of the
Class A Acquiring Fund Shares received by each holder of Class A Acquired Fund
Shares is approximately equal to the fair market value of the Class A Acquired
Fund Shares surrendered by such shareholder, and the fair market value of the
Class B Acquiring Fund Shares received by each holder of Class B Acquired Fund
Shares is approximately equal to the fair market value of the Class B Acquired
Fund Shares surrendered by such shareholder.

        (q)  There is no plan or intention on the part of any shareholder of
Acquired Fund that owns beneficially 5% or more of the Acquired Fund Shares
and, to the best knowledge of management of Acquired Fund, there is no plan or
intention on the part of the remaining shareholders of Acquired Fund to sell,
redeem, exchange or otherwise dispose of a number of the Acquiring Fund Shares
received in the transaction that would reduce the aggregate ownership of the
Acquiring Fund Shares by former Acquired Fund shareholders to a number of
shares having a value, as of the date

of the transaction, of less than fifty percent (50%) of the value of
all of the formerly outstanding Acquired Fund Shares as of the same date. 
Shares of Acquired Fund and Acquiring Fund held by Acquired Fund shareholders
and sold, redeemed, exchanged or otherwise disposed of prior or subsequent to
the transaction as part of the plan of reorganization are taken into account
for purposes of this representation.

        (r)  Acquired Fund assets transferred to Acquiring Fund comprise at
least ninety percent (90%) of the fair market value of the net assets and at
least seventy percent (70%) of the fair market value of the gross assets held
by Acquired Fund immediately prior to the transaction.  For purposes of this
representation, amounts used by Acquired Fund to pay its outstanding
liabilities, including reorganization expenses, and all redemptions and
distributions (except for redemptions in the ordinary course of business upon
demand of a shareholder that Acquired Fund is required to make as an open-end
investment company pursuant to Section 22(e) of the 1940 Act and regular,
normal dividends, which dividends include any final distribution of previously
undistributed investment company taxable income and net capital gain for
Acquired Fund's final taxable year ending on the closing date of the
transaction) made by Acquired Fund immediately preceding the transaction are
taken into account as assets of Acquired Fund held immediately prior to the
transaction.

        (s)  The Acquired Fund Liabilities assumed by Acquiring Fund plus the
liabilities, if any, to which the transferred assets are subject were incurred
by Acquired Fund in the ordinary course of its business or are expenses of the
transaction.

        (t)  The fair market value of the Acquired Fund assets transferred to
Acquiring Fund equals or exceeds the sum of the Acquired Fund Liabilities
assumed by Acquiring Fund and the amount of liabilities, if any, to which the
transferred assets are subject.

        (u)  The total adjusted basis of the Acquired Fund assets transferred
to Acquiring Fund equals or exceeds the sum of the Acquired Fund Liabilities
assumed by Acquiring Fund and the amount of liabilities, if any, to which the
transferred assets are subject.

        (v)  Acquired Fund does not pay compensation to any shareholder-
employee.

                                   OPINION
                                   -------

        On the basis of and subject to the foregoing and in reliance upon the
representations described above, and provided that any statement of fact
represented to be made to the best knowledge of management of Acquired Fund or
Acquiring Fund is in fact true and correct (whether or not known), we are of
the opinion that

        (a)  The acquisition by Acquiring Fund of all of the assets of Acquired
Fund solely in exchange for the issuance of Acquiring Fund Shares to Acquired
Fund and the assumption of all of the Acquired Fund Liabilities by Acquiring
Fund, followed by the distribution by Acquired Fund, in liquidation of Acquired
Fund, of Acquiring Fund Shares to Acquired Fund shareholders in exchange for
their Acquired Fund Shares and the termination of Acquired Fund, will
constitute a "reorganization" within the meaning of Section 368(a)(1)(D) of the
Code.  Acquiring Fund and Acquired Fund will each be "a party to a
reorganization" within the meaning of Section 368(b) of the Code.

        (b)  No gain or loss will be recognized by Acquired Fund upon (i) the
transfer of all of its assets to Acquiring Fund solely in exchange for the
issuance of Acquiring Fund Shares to Acquired Fund and the assumption of all of
the Acquired Fund Liabilities by Acquiring Fund and (ii) the distribution by
Acquired Fund of such Acquiring Fund Shares to the shareholders of Acquired
Fund (Sections 361(a) and 361(c) of the Code).

        (c)  No gain or loss will be recognized by Acquiring Fund upon the
receipt of the assets of Acquired Fund solely in exchange for the issuance of
Acquiring Fund Shares to Acquired Fund and the assumption of all of the
Acquired Fund Liabilities by Acquiring Fund (Section 1032(a) of the Code).

        (d)  The basis of the assets of Acquired Fund acquired by Acquiring
Fund will be, in each instance, the same as the basis of such assets in the
hands of Acquired Fund immediately prior to the transfer (Section 362(b) of the
Code).

        (e)  The tax holding period of the assets of Acquired Fund in the hands
of Acquiring Fund will, in each instance, include Acquired Fund's tax holding
period for those assets (Section 1223(2) of the Code).

        (f)  The shareholders of Acquired Fund will not recognize gain or loss
upon the exchange of all of their Acquired Fund Shares solely for Acquiring
Fund Shares as part of the transaction (Section 354(a)(l) of the Code).

        (g)  The basis of the Acquiring Fund Shares received by the Acquired
Fund shareholders in the transaction will be the same as the basis of the
Acquired Fund Shares surrendered in exchange therefor (Section 358(a)(1) of the
Code).

        (h)  The tax holding period of the Acquiring Fund Shares received by
Acquired Fund shareholders will include, for each shareholder, the tax holding
period for the Acquired Fund Shares surrendered in exchange therefor, provided
the Acquired Fund Shares were held as capital assets on the date of the
exchange (Section 1223(1) of the Code).

        No opinion is expressed or implied regarding the federal income tax
consequences to Acquiring Fund, Acquired Fund or Acquired Fund shareholders of
any conditions existing at the time of, effects resulting from, or other
aspects of the transaction except as expressly set forth above.  

                                        Very truly yours,

reorganization of the Fund, as described below.
            
Under the terms of the reorganization, subject to shareholder approval at a

transfer all of its assets and liabilities to John Hancock Tax-Free Bond Fund
("Tax-Free Bond Fund") in a tax-free exchange for shares of equal value of
Tax-Free Bond Fund.  Further information regarding the proposed reorganization
will be contained in a proxy statement and prospectus which is scheduled to be

Effective March 6, 1996, John Hancock Tax-Exempt Income Fund will be closed

INVESTMENT OBJECTIVE AND POLICIES

THE FUND'S INVESTMENT OBJECTIVE IS TO SEEK AS HIGH A LEVEL OF DIVIDEND INCOME
EXEMPT FROM FEDERAL INCOME TAX AS IS CONSISTENT WITH PRESERVATION OF CAPITAL.

The Fund's investment objective is to provide as high a level of dividend income
exempt from Federal income tax as is consistent with preservation of capital and
the Fund's requirements for liquidity. The Fund seeks to achieve its objective
by investing in a diversified portfolio of municipal bonds and other securities
(including certain industrial development or private activity bonds), the
interest on which is, at the time of issue, excludable from gross income for
Federal income tax purposes in the opinion of bond counsel to the issuer (all of
which are commonly known as "Tax-Exempt Bonds"). There is no assurance that the
Fund will achieve its investment objective.

The Fund's assets may consist of Tax-Exempt Bonds, short-term municipal debt
instruments (Tax-Exempt Bonds issued for terms of less than one year), cash,
receivables, and short-term taxable investments, which include securities such
as (1) U.S. Treasury obligations; (2) obligations of agencies and
instrumentalities of the United States government; and (3) money market
instruments, such as domestic bank certificates of deposit, repurchase
agreements, finance company and other corporate commercial paper and bankers'
acceptances. It is not expected that the portion of the Fund's total assets
consisting of short-term taxable investments will exceed 15%.

It is expected that at least 85% of the Fund's total assets will consist of
Tax-Exempt Bonds, the interest on which is not treated as a tax preference item
under the Federal alternative minimum tax; and that at least 65% of the Fund's
investments in Tax-Exempt Bonds will consist of bonds falling into either of two
categories:

1. Tax-Exempt Bonds that, at the time of investment, have a rating within the
   three highest ratings determined by Moody's Investors Service, Inc.
   ("Moody's") (Aaa, Aa, and A), by Standard and Poor's Ratings Group ("Standard
   & Poor's") (AAA, AA, and A) or by Fitch Investor Services, Inc. ("Fitch")
   (AAA, AA, A), and

2. Tax-Exempt Bonds issued for terms of less than one year (short-term municipal
   debt instruments) that (a) have a rating within the three highest ratings as
   determined by Moody's (MIG 1, MIG 2, or MIG 3), by Standard & Poor's
   (SP-1,SP-2, SP-3) or by Fitch (F-1, F-2, F-3) or (b) bear no rating but are,
   in the judgment of John Hancock Advisers, Inc. ("the Adviser"), of equivalent
   quality to a MIG 3, SP-3 or F-3 rating or better. Not more than 25% of the
   value of the Fund's total assets will under normal market conditions, be
   invested in short-term Tax-Exempt instruments.

The portion of the Fund's investment in Tax-Exempt Bonds not falling within
either of the two foregoing categories may consist of Tax-Exempt Bonds that, at
the time of investment, are rated within the next three highest ratings (Baa,
Ba, B or BBB, BB or B) or their equivalent, and unrated Tax-Exempt Bonds of
comparable quality as determined by the Adviser. The Fund's investment in
long-term Tax-Exempt Bonds that are not rated will not, however, exceed 20% of
the Fund's investments in Tax-Exempt Bonds. It will be limited to those which,
in the judgment of the Adviser, are of equivalent quality to Tax-Exempt Bonds in
the rating categories noted above. Bonds which have a rating of BBB or lower,
Baa or lower or an equivalent rating, and unrated bonds of comparable quality,
are considered speculative. While generally providing greater income than
investments in higher quality securities, these bonds involve greater risk of
principal and income loss, including the possibility of default. These bonds may
have greater price volatility, especially during periods of economic uncertainty
or change. Bonds rated B are currently meeting debt service requirements but
provide a limited margin of safety and are vulnerable to default in the event of
adverse business, financial or economic conditions. The bonds are considered
highly speculative. In addition, the market for bonds rated BBB, Baa or lower
may be less liquid than the market for higher rated securities. Therefore, the
Adviser's judgment may at times play a greater role in the performance and
valuation of the Fund's investments in these bonds.

The two principal classifications of municipal securities in which the Fund may
invest are "general obligation" and "revenue" bonds. General obligation bonds

<PAGE>   7

are secured by the issuer's pledge of its full faith and credit and taxing power
for the payment of principal and interest. Revenue bonds are payable only from
the revenues derived from a particular facility or class of facilities or a
specific revenue source, and generally are not payable from the unlimited
revenues of the issuer. The Fund may also invest up to 5% of its net assets in
certificates of participation in municipal lease obligations.

The Fund's investments in Tax-Exempt Bonds entail certain risks. These include
adverse income and principal value fluctuation associated with economic
conditions affecting the market for Tax-Exempt Bonds in general, the
creditworthiness of issuers and guarantors of these securities and the
facilities financed by them; and adverse interest rate changes. The value of the
Fund's investments in Tax-Exempt Bonds, and thus the net asset value of the
Fund's shares, can generally be expected to vary inversely with changes in
interest rates.

It is expected that, under normal market conditions, the Fund's average
portfolio maturity will range from 20 to 25 years. Portfolio securities with
longer maturities generally are more susceptible to adverse interest rate
changes than securities with shorter maturities.

LENDING OF SECURITIES. The Fund may lend portfolio securities to brokers,
dealers, and financial institutions if the loan is collateralized by cash or
U.S. Government securities according to applicable regulatory requirements. The
Fund may reinvest any cash collateral in short-term securities. When the Fund
lends portfolio securities, there is a risk that the borrower may fail to return
the securities. As a result, the Fund may incur a loss or, in the event of the
borrower's bankruptcy, the Fund may be delayed in or prevented from liquidating
the collateral. It is a fundamental policy of the Fund not to lend portfolio
securities having a total value exceeding 33 1/3% of its total assets.

THE FUND MAY EMPLOY CERTAIN INVESTMENT STRATEGIES TO ACHIEVE ITS INVESTMENT
OBJECTIVE.

RESTRICTED SECURITIES. The Fund may purchase restricted securities, including
those that can be offered and sold to "qualified institutional buyers" under
Rule 144A under the Securities Act of 1933 (the "Securities Act"). The Trustees
will monitor the Fund's investments in these securities, focusing on certain
factors, including valuation, liquidity and availability of information.
Purchases of restricted securities are subject to an investment restriction
limiting all the Fund's illiquid securities to not more than 15% of its net
assets.

REPURCHASE AGREEMENTS, FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. The Fund
may enter into repurchase agreements and may purchase securities on a forward
commitment or when-issued basis. In a repurchase agreement, the Fund buys a
security subject to the right and obligation to sell it back to the seller at a
higher price. These transactions must be fully collateralized at all times, but
involve some credit risk to the Fund if the other party defaults on its
obligation and the Fund is delayed in or prevented from liquidating the
collateral. The Fund will segregate in a separate account cash or liquid, high
grade debt securities equal in value to its forward commitments and when-issued
securities. Purchasing securities for future delivery or on a when-issued basis
may increase the Fund's overall investment exposure and involve a risk of loss
if the value of the securities declines before the settlement date.

FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may buy and sell municipal
bond index futures contracts, interest rate futures contracts and related
options. It may make these investments either to hedge against changes in
securities prices, interest rates and other market conditions, or for
speculative purposes. Transactions in these contracts involve a risk of loss or
depreciation due to unanticipated adverse changes in interest rates or
securities prices. The loss on futures contracts and written options may exceed
the Fund's initial investment in these contracts. In addition, the Fund may lose
the entire premium paid for purchased options that cannot be profitably
exercised by the Fund. The Fund's success in using futures and options on
futures to hedge portfolio assets depends on the degree of price correlation
between the derivative instrument and the hedged asset. The Fund's futures
contracts and options on futures will be traded on a U.S. commodity exchange or

<PAGE>   8

board of trade. Futures contracts and options on futures may become illiquid
under adverse market conditions and may be subject to trading limitations
imposed by a commodity exchange. The Fund will not engage in a futures or
options transaction for speculative purposes, if immediately thereafter, the sum
of initial margin deposits on existing positions and premiums required to
establish these speculative positions exceeds 5% of the Fund's net assets.

VARIABLE AND FLOATING-RATE OBLIGATIONS. The Fund may invest in variable rate and
floating rate obligations on which the interest may fluctuate based on changes
in market rates. The interest rates payable on variable rate obligations are
adjusted at designated periodic intervals. The interest rates payable on
floating rate obligations are adjusted whenever there is a change in the market
interest rate on which the interest payable is based.

SHORT-TERM TRADING. Short-term trading means the purchase and subsequent sale of
a security after it has been held for a relatively brief period of time. The
Fund engages in short-term trading in response to changes in interest rates or
other economic trends and developments, or to take advantage of yield
disparities between various fixed-income securities in order to realize capital
gains or improve income. Portfolio turnover rates of the Fund for recent years
are shown in the section "The Fund's Financial Highlights."

CERTAIN INVESTMENTS MAY BE SUBJECT TO THE ALTERNATIVE MINIMUM TAX.

The Fund may invest in certain types of Tax-Exempt Bonds on which the interest
income is treated as an item of tax preference for purposes of the Federal
alternative minimum tax. To the extent the Fund invests in these Tax-Exempt
Bonds as described above, shareholders will be required to treat as a Federal
income tax preference item that part of the Fund's distributions that is derived
from interest on these Tax-Exempt Bonds. Dividends derived from interest income
from all Tax-Exempt Bonds are included in corporate "adjusted current earnings"
for purposes of computing the alternative minimum taxable income of corporate
shareholders of the Fund.

THE FUND FOLLOWS CERTAIN POLICIES, WHICH MAY HELP TO REDUCE INVESTMENT RISK.

INVESTMENT RESTRICTIONS. The Fund has adopted certain investment restrictions
that are detailed in the Statement of Additional Information, where they are
classified as fundamental or non-fundamental. The Fund's investment restrictions
designated as fundamental may not be changed without shareholder approval. The
Fund's investment objective and all other investment policies and restrictions,
however, are nonfundamental and can be changed by a vote of the Trustees without
shareholder approval. These changes may result in the Fund having an investment
objective different from the objective you considered appropriate at the time of
your investment. The Fund's portfolio turnover rates for recent years are shown
in the section "The Fund's Financial Highlights."

BROKERS ARE CHOSEN ON BEST PRICE AND EXECUTION.

When choosing brokerage firms to carry out the Fund's transactions, the Adviser
gives primary consideration to execution at the most favorable price, taking
into account the broker's professional ability and quality of service.
Consideration may also be given to the broker's sales of Fund shares. Pursuant
to procedures established by the Trustees, the Adviser may place securities
transactions with brokers affiliated with the Adviser. These brokers include
Tucker Anthony Incorporated, John Hancock Distributors, Inc. and Sutro &

ORGANIZATION AND MANAGEMENT OF THE FUND

THE TRUSTEES ELECT OFFICERS AND RETAIN THE INVESTMENT ADVISER WHO IS RESPONSIBLE
FOR THE DAY-TO-DAY OPERATIONS OF THE FUND, SUBJECT TO THE TRUSTEES' POLICIES AND
SUPERVISION.

The Fund is a diversified open-end management investment company organized as a
Massachusetts business trust in 1976. The Fund has an unlimited number of
authorized shares of beneficial interest. The Fund's Declaration of Trust

<PAGE>   9

permits the Trustees, without shareholder approval, to create and classify
shares of beneficial interest into separate series of the Fund. As of the date
of this Prospectus, the Trustees have not authorized the creation of any new
series of the Fund. Although additional series may be added in the future, the
Trustees have no current intention of creating additional series of the Fund.
The Trust's Declaration of Trust also permits the Trustees to classify and
reclassify any series or portfolio of shares into one or more classes.
Accordingly, the Trustees have authorized the issuance of two classes of the
Fund, designated Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund. Each class has equal
rights as to voting, redemption, dividends and liquidation. However, each class
bears different distribution and transfer agent fees and other expenses. Also,
Class A and Class B shareholders have exclusive voting rights with respect to
their distribution plans.

Shareholders have certain rights to remove Trustees. The Fund is not required
and does not intend to hold annual shareholder meetings, although special
meetings may be held for such purposes as electing or removing Trustees,
changing fundamental restrictions and policies or approving a management
contract. The Fund, under certain circumstances, will assist in shareholder
communications with other shareholders.

JOHN HANCOCK ADVISERS, INC. ADVISES INVESTMENT COMPANIES HAVING A TOTAL ASSET
VALUE OF MORE THAN $13 BILLION.

The Adviser was organized in 1968 and is a wholly-owned indirect subsidiary of
the John Hancock Mutual Life Insurance Company, a financial services company. It
provides the Fund, and other investment companies in the John Hancock group of
funds, with investment research and portfolio management services. John Hancock
Funds, Inc. ("John Hancock Funds") distributes shares for all of the John
Hancock funds through selected broker-dealers ("Selling Brokers"). Certain Fund
officers are also officers of the Adviser and John Hancock Funds. Pursuant to an
order granted by the Securities and Exchange Commission, the Fund has adopted a
deferred compensation plan for its independent Trustees which allows Trustees'
fees to be invested by the Fund in other John Hancock funds.

Thomas C. Goggins is Senior Vice President and portfolio manager of the Fund.
Mr. Goggins heads up John Hancock's team of municipal bond portfolio managers
and analysts. He joined the Adviser in 1995. Previously to that date, Mr.
Goggins was a municipal bond portfolio manager at Putnam Investments and
Transamerica Investment Services, Inc.

In order to avoid any conflict with portfolio trades for the Fund, the Adviser
and the Fund have adopted extensive restrictions on personal securities trading
by personnel of the Adviser and its affiliates. Some of these restrictions are:
preclearance for all personal trades and a ban on the purchase of initial public
offerings, as well as contributions to specified charities of profits on
securities held for less then 91 days. These restrictions are a continuation of
the basic principle that the interests of the Fund and its shareholders come
first.

ALTERNATIVE PURCHASE ARRANGEMENTS

AN ALTERNATIVE PURCHASE PLAN ALLOWS YOU TO CHOOSE THE METHOD OF PURCHASE THAT IS
BEST FOR YOU.

You can purchase shares of the Fund at a price equal to their net asset value
per share, plus a sales charge. At your election, this charge may be imposed
either at the time of the purchase (see "Initial Sales Charge Alternative--
Class A shares") or on a contingent deferred basis (see "Contingent Deferred
Sales Charge Alternative--Class B shares"). If you do not specify on your
account application the class of shares you are purchasing, it will be assumed
that you are investing in Class A shares.

INVESTMENTS IN CLASS A SHARES ARE SUBJECT TO AN INITIAL SALES CHARGE.

CLASS A SHARES. If you elect to purchase Class A shares, you will incur an
initial sales charge unless your purchase is $1 million or more. If you purchase
$1 million or more of Class A shares, you will not be subject to an initial
sales charge, but you will incur a sales charge if you redeem your shares within
one year of purchase. Class A shares are subject to ongoing distribution and

<PAGE>   10

service fees at a combined annual rate of up to 0.30% of the Fund's average
daily net assets attributable to the Class A shares. Certain purchases of Class
A shares qualify for reduced initial sales charges. See "Share Price --
Qualifying for a Reduced Sales Charge."

INVESTMENTS IN CLASS B SHARES ARE SUBJECT TO A CONTINGENT DEFERRED SALES CHARGE.

CLASS B SHARES. You will not incur a sales charge when you purchase Class B
shares, but the shares are subject to a sales charge if you redeem them within
six years of purchase (the"contingent deferred sales charge" or the "CDSC").
Class B shares are subject to ongoing distribution and service fees at a
combined annual rate of up to 1.00% of the Fund's average daily net assets
attributable to the Class B shares. Investing in Class B shares permits all of
your dollars to work from the time you make your investment, but the higher
ongoing distribution fee will cause these shares to have higher expenses than
that of Class A shares. To the extent that any dividends are paid by the Fund,
these higher expenses will result in lower dividends than those paid on Class A
shares.

Class B shares are not available to full-service defined contribution plans
administered by Investor Services or John Hancock Mutual Life Insurance Company
that had more than 100 eligible employees at the inception of the Fund
account.

FACTORS TO CONSIDER IN CHOOSING AN ALTERNATIVE

YOU SHOULD CONSIDER WHICH CLASS OF SHARES WOULD BE MORE BENEFICIAL FOR YOU.

The alternative purchase arrangement allows you to choose the most beneficial
way to buy shares, given the amount of your purchase, the length of time you
expect to hold your shares and other circumstances. You should consider whether,
during the anticipated life of your Fund investment, the CDSC and accumulated
fees on Class B shares would be less than the initial sales charge and
accumulated fees on Class A shares purchased at the same time; and to what
extent this differential would be offset by the Class A shares' lower expenses.
To help you make this determination, the table under the caption "Expense
Information" on page 2 of this Prospectus gives examples of the charges
applicable to each class of shares. Class A shares will normally be more
beneficial if you qualify for a reduced sales charge. See "Share Price--
Qualifying for a Reduced Sales Charge."

Class A shares are subject to lower distribution and service fees and,
accordingly, pay correspondingly higher dividends per share, to the extent that
any dividends are paid. However, because initial sales charges are deducted at
the time of purchase, you would not have all of your funds invested initially
and, therefore, would initially own fewer shares. If you do not qualify for
reduced initial sales charges and expect to maintain your investment for an
extended period of time, you might consider purchasing Class A shares. This is
because the accumulated distribution and service charges on Class B shares may
exceed the initial sales charge and accumulated distribution and service charges
on Class A shares during the life of your investment.

Alternatively, you might determine that it is more advantageous to purchase
Class B shares to have all your funds invested initially. However, you will be
subject to higher distribution fees and, for a six-year period, a CDSC.

In the case of Class A shares, distribution expenses that John Hancock Funds
incurs in connection with the sale of shares will be paid from the proceeds of
the initial sales charge and the ongoing distribution and service fees. In the
case of Class B shares, expenses will be paid from the proceeds of the ongoing
distribution and service fees, as well as from the CDSC incurred upon redemption
within six years of purchase. The purpose and function of the Class B shares'
CDSC and ongoing distribution and service fees are the same as those of the
Class A shares' initial sales charge and ongoing distribution and service fees.
Sales personnel distributing the Fund's shares may receive different
compensation for selling each class of shares.

Dividends, if any, on Class A and Class B shares will be calculated in the same
manner, at the same time and on the same day. They will also be in the same
amount, except for differences resulting from each class bearing only its own
distribution and service fees, shareholder meeting expenses and any incremental

<PAGE>   11

transfer agency costs. See "Dividends and Taxes."

THE FUND'S EXPENSES

For managing its investment and business affairs, the Fund pays a fee to the
Adviser which for the 1994 fiscal year, was 0.55% of the Fund's average daily
net asset value.

THE FUND PAYS DISTRIBUTION AND SERVICE FEES FOR MARKETING AND SALES- RELATED
SHAREHOLDER SERVICING.

The Class A and Class B shareholders have adopted distribution plans (each a
"Plan") pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under
these Plans, the Fund will pay distribution and service fees at an aggregate
annual rate of 0.30% of the Class A shares' average daily net assets and an
aggregate annual rate of 1.00% of the Class B shares' average daily net assets.
In each case, up to 0.25% is for service expenses and the remaining amount is
for distribution expenses. Distribution fees are used to reimburse John Hancock
Funds for its distribution expenses including but not limited to: (i) initial
and ongoing sales compensation to Selling Brokers and others (including
affiliates of John Hancock Funds) engaged in the sale of Fund shares; (ii)
marketing, promotional and overhead expenses incurred in connection with the
distribution of Fund shares; and (iii) with respect to Class B shares only,
interest expenses on unreimbursed distribution expenses. In the event John
Hancock Funds is not fully reimbursed for payments made or expenses incurred by
it under the Class A Plan, these expenses will not be carried beyond one year
from the date they were incurred. These unreimbursed expenses under the Class B
Plan will be carried forward together with interest on the balance of these
unreimbursed expenses. For the fiscal year ended December 31, 1994 an aggregate
of $175,709 of distribution expenses or 8.5% of the average net assets of the
Class B shares of the Fund, was not reimbursed or recovered by the John Hancock
Funds through the receipt of deferred sales charges or 12b-1 fees in prior
periods.

Information on the Fund's total expenses is in the Fund's Financial Highlights
section of this Prospectus.

DIVIDENDS AND TAXES

Dividends from the Fund's net investment income are generally declared daily and
distributed monthly. Capital gains, if any, are generally distributed annually.
Dividends are reinvested in additional shares of your class unless you elect the
option to receive them in cash. If you elect the cash option and the U.S. Postal
Service cannot deliver your checks, your election will be converted to the
reinvestment option. Because of the higher expenses associated with Class B
shares, any dividend on Class B shares will be lower than that on Class A
shares. See "Share Price."

IN 1992, 1993 AND 1994, 99.8%, 99.8% AND 99.7%, RESPECTIVELY, OF THE FUND'S
INCOME DIVIDENDS WERE EXEMPT FROM FEDERAL INCOME TAX.

TAXATION. The Fund intends to satisfy applicable tax requirements so that
interest earned by the Fund from Tax-Exempt Bonds will be federally tax-free
when paid to you as income distributions. Dividends derived from interest on
certain Tax-Exempt Bonds that are "private activity bonds" may, however,
increase the Federal alternative minimum tax liability of shareholders that are
subject to the individual alternative minimum tax, and all tax-exempt dividends
may increase a corporate shareholder's liability, if any, for the federal
alternative minimum tax.

Shareholders receiving social security benefits and certain railroad retirement
benefits may be subject to federal income tax on a portion of such benefits as a
result of receiving investment income, including tax-exempt income (such as
exempt-interest) and other dividends paid by the Fund. The Fund may not be an
appropriate investment for persons who are "substantial users" of facilities
financed by industrial development or private activity bonds or persons related

<PAGE>   12

to substantial users. Consult your tax adviser if you think this may apply to
you.

Certain of the Fund's permitted investments may produce taxable income or
capital gains. Dividends from any net short-term capital gains or any taxable
income the Fund earns, including accrued market discount included in the Fund's
income, are taxable to you as ordinary income and dividends from the Fund's net
long-term capital gains are taxable as long-term capital gains. These dividends
are taxable, whether received in cash or reinvested in additional shares.
Certain dividends paid by the Fund in January of a given year may be taxable as
if you received them the previous December. The Fund will send you a statement
by January 31 showing the tax status of the dividends you received for the prior
year.

The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). As a regulated investment company, the Fund will not be
subject to Federal income tax on any net investment income and net realized
capital gains that are distributed to its shareholders at least annually. When
you redeem (sell) or exchange shares, you may realize a taxable gain or loss.

On the account application, you must certify that your social security or other
taxpayer identification number is correct and that you are not subject to backup
withholding of Federal income tax. If you do not provide this information or are
otherwise subject to backup withholding, the Fund may be required to withhold
31% of your taxable dividends and the proceeds of redemptions and exchanges.

In addition to Federal taxes with respect to any taxable dividends, you may be
subject to state, local or foreign taxes, depending on your residence. In some
states, a portion of the Fund's dividends which represents interest received by
the Fund on direct U.S. government obligations is exempt from tax. Some states
and localities exempt Fund distributions of interest on their own municipal
obligations. You will receive tax information each year showing the percentage
of the Fund's dividends attributable to obligations of each state. Non-U.S.
shareholders and tax-exempt shareholders are subject to different tax treatment
not described above. You should consult your tax adviser for specific advice.

PERFORMANCE

THE FUND MAY ADVERTISE ITS YIELD AND TOTAL RETURN.

Yield reflects the Fund's rate of income on portfolio investments as a
percentage of its share price. Yield is computed by annualizing the result of
dividing the net investment income per share over a 30 day period by the maximum
offering price per share on the last day of that period. Yield is calculated
according to accounting methods that are standardized for all stock and bond
funds. Because yield accounting methods differ from the methods used for other
accounting purposes, the Fund's yield may not equal the income paid on your
shares or the income reported in the Fund's financial statements. The Fund may
also quote a tax-equivalent yield, which shows the taxable yield you would have
to earn before taxes to equal the Fund's tax-free yield. A tax-equivalent yield
is calculated by dividing the Fund's tax-free yield by one minus a stated tax
rate.

The Fund's total return shows the overall change in value of a hypothetical
investment in the Fund, assuming the reinvestment of all dividends. Cumulative
total return shows the Fund's performance over a period of time. Average annual
total return shows the cumulative return of the Fund shares divided over the
number of years included in the period. Because average annual total return
tends to smooth out variations in the Fund's performance, you should recognize
that it is not the same as actual year-to-year results.

Both total return and yield calculations for Class A shares generally include
the effect of paying the maximum sales charge (except as shown in "The Fund's
Financial Highlights"). Investments at lower sales charges would result in
higher performance figures. Yield and total return for the Class B shares
reflect the deduction of the applicable CDSC imposed on a redemption of shares
held for the applicable period. All calculations assume that all dividends are
reinvested at net asset value on the reinvestment dates during the periods.
Yield and total return of Class A and Class B shares will be calculated
separately, and, because each class is subject to different expenses, the yield
or total return may differ with respect to that class for the same period. The

<PAGE>   13

relative performance of the Class A and Class B shares will be affected by a
variety of factors, including the higher operating expenses attributable to the
Class B shares, whether the Fund's investment performance is better in the
earlier or later portions of the period measured and the level of net assets of
the classes during the period. The Fund will include the total return of both
classes in any advertisement or promotional materials including the Fund's
performance data. The value of Fund shares, when redeemed, may be more or less
than their original cost. Both yield and total return are historical
calculations, and are not indications of future performance. See "Factors to
Consider in Choosing an Alternative."

You will receive a statement of your account after any transaction that affects
your share balance or registration (statements related to reinvestment of
dividends and automatic investment/withdrawal plans will be sent to you
quarterly). A tax information statement will be mailed to you by January 31 of
each year.

SHARE PRICE

THE OFFERING PRICE OF YOUR SHARES IS THEIR NET ASSET VALUE PLUS A SALES CHARGE,
IF APPLICABLE, WHICH WILL VARY WITH THE PURCHASE ALTERNATIVE YOU CHOOSE.

The net asset value per share ("NAV") is the value of one share. The NAV of each
class can differ. Securities in the Fund's portfolio are valued on the basis of
market quotations, valuations provided by independent pricing services, or at
fair value as determined in good faith according to procedures approved by the
Trustees. Short-term debt investments maturing within 60 days are valued at
amortized cost which approximates market value. The NAV is calculated once daily
as of the close of regular trading on the New York Stock Exchange (generally at

<PAGE>   15

4:00 p.m., New York time) on each day that the Exchange is open.

Shares of the Fund are sold at the offering price based on the NAV computed
after your investment request is received in good order by John Hancock Funds.
If you buy shares of the Fund through a Selling Broker, the Selling Broker must
receive your investment before the close of regular trading on the New York
Stock Exchange, and transmit it to John Hancock Funds before its close of
business, to receive that day's offering price.

INITIAL SALES CHARGE ALTERNATIVE -- CLASS A SHARES. The offering price you pay
for Class A shares of the Fund equals the NAV plus a sales charge, as follows:

<F1> Upon notice to Selling Brokers with whom it has sales agreements, John
     Hancock Funds may reallow an amount up to the full applicable sales charge.
     In addition to the reallowance allowed to all Selling Brokers, John Hancock
     Funds will pay the following: round trip airfare to a resort will be
     offered to each registered representative of a Selling Broker (if the
     Selling Broker has agreed to participate) who sells certain amounts of
     shares of John Hancock funds. John Hancock Funds will make these incentive
     payments out of its own resources. Other than distribution fees, the Fund
     does not bear distribution expenses. A Selling Broker to whom substantially
     the entire sales charge is reallowed or who receives these incentives may
     be deemed to be an underwriter under the Securities Act of 1933.

<F2> No sales charge is payable at the time of purchase of Class A shares of $1
     million or more, but a contingent deferred sales charge may be imposed in
     the event of certain redemption transactions within one year of purchase.

<F3> John Hancock Funds may pay a commission and first year's service fee (as
     described in (+) below) to Selling Brokers who initiate and are
     responsible for purchases of $1 million or more of shares in aggregate, as
     follows: 1% on sales to $4,999,999, plus 0.50% on the next $5 million and
     0.25% on $10 million and over.

<F4> At the time of sale, John Hancock Funds pays to Selling Brokers the first
     year's service fee in advance, in an amount equal to 0.25% of the net
     assets invested in the Fund. Thereafter it pays the service fee
     periodically in arrears in an amount up to 0.25% of the Fund's average
     annual net assets. Selling Brokers receive the fee as compensation for
     providing personal and account maintenance services to shareholders.

</TABLE>

Sales charges ARE NOT APPLIED to any dividends that are reinvested in additional
shares of the Fund.

John Hancock Funds will pay certain affiliated Selling Brokers at an annual rate
of up to 0.05% of the daily net assets of the accounts attributable to these
brokers.

Under certain circumstances described below, investors in Class A shares may
be entitled to pay reduced sales charges. See "Qualifying For a Reduced Sales
Charge" below.

CONTINGENT DEFERRED SALES CHARGE -- INVESTMENTS OF $1 MILLION OR MORE IN CLASS A
SHARES. Purchases of $1 million or more of Class A shares will be made at net

<PAGE>   16

asset value with no initial sales charge, but if the shares are redeemed within
12 months after the end of the calendar month in which the purchase was made
(the contingent deferred sales charge period), a contingent deferred sales
charge ("CDSC") will be imposed. The rate of the CDSC will depend on the amount
invested as follows:

<TABLE>
             AMOUNT INVESTED                                        CDSC RATE

<S>                                                                   <C>
$1 million to $4,999,999                                              1.00%
Next $5 million to $9,999,999                                         0.50%
Amounts of $10 million and over                                       0.25%

</TABLE>
The charge will be assessed on an amount equal to the lesser of the current
market value or the original purchase cost of the redeemed Class A shares
redeemed. Accordingly, no CDSC will be imposed on increases in account value
above the initial purchase price, including any dividends which have been
reinvested in additional Class A shares.

In determining whether a CDSC is applicable to a redemption, the calculation
will be determined in a manner that results in the lowest possible rate being
charged. Therefore, it will be assumed that the redemption is first made from
any shares in your account that are not subject to the CDSC. The CDSC is waived
on redemption in certain circumstances. See the discussion under "Waiver of
Contingent Deferred Sales Charges".

YOU MAY QUALIFY FOR A REDUCED SALES CHARGE ON YOUR INVESTMENTS IN CLASS A
SHARES.

QUALIFYING FOR A REDUCED SALES CHARGE. If you invest more than $100,000 in Class
A shares of the Fund or a combination of funds in the John Hancock funds (except
money market funds), you may qualify for a reduced sales charge on your
investments in Class A shares through a LETTER OF INTENTION. You may also be
able to use the ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE to take
advantage of the value of your previous investments in Class A shares of the
John Hancock funds when meeting the breakpoints for a reduced sales charge. For
the ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE, the applicable sales
charge will be based on the total of:

1. Your current purchase of Class A shares of the Fund;

2. The net asset value (at the close of business on the previous day) of (a) all
Class A shares of the Fund you hold, and (b) all Class A shares of any John
Hancock funds you hold; and

3. The net asset value of all shares held by another shareholder eligible to
combine his or her holdings with you into a single "purchase."

EXAMPLE:

If you hold Class A shares of a John Hancock fund with a net asset value of
$80,000, and subsequently invest $20,000 in Class A shares of the Fund, the
sales charge on this subsequent investment would be 3.75% and not 4.50%. This
rate is the rate that would otherwise be applicable to investments of less than
$100,000. See "Initial Sales Charge Alternative--Class A Shares."

If you are in one of the following categories, you may purchase Class A shares
of the Fund without paying a sales charge:

FUND EMPLOYEES AND AFFILIATES

* A Trustee or officer of the Fund; a Director or officer of the Adviser and its
  affiliates or Selling Brokers; employees or sales representatives of any of
  the foregoing; retired officers, employees or Directors of any of the
  foregoing; a member of the immediate family of any of the foregoing; or any
  fund, pension, profit sharing or other benefit plan for the individuals
  described above.

<PAGE>   17

SPECIAL TRANSACTIONS

* Any state, county, city or any instrumentality, department, authority or
  agency of these entities that is prohibited by applicable investment laws from
  paying a sales charge or commission when it purchases shares of any registered
  investment management company.*

* A bank, trust company, credit union, savings institution or other type of
  depository institution, its trust departments or common trust funds (an
  "eligible depository institution") if it is purchasing $1 million or more for
  non-discretionary customers or accounts.*

* A broker, dealer or registered investment adviser that has entered into an
  agreement with John Hancock Funds providing specifically for the use of Fund
  shares in fee-based investment products made available to their clients.

* A former participant in an employee benefit plan with John Hancock funds, when
  he/she withdraws from his/her plan and transfers any or all of his/her plan
  distributions directly to the Fund.

- ---------
* For investments made under these provisions, John Hancock Funds may make a
  payment out of its own resources to the Selling Broker in an amount not to
  exceed 0.25% of the amount invested.

Class A shares of the Fund may also be purchased without an initial sales charge
in connection with certain liquidation, merger or acquisition transactions
involving other investment companies or personal holding companies.

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE -- CLASS B SHARES. Class B shares
are offered at net asset value per share without a sales charge, so that your
entire initial investment will go to work at the time of purchase. However,
Class B shares redeemed within six years of purchase will be subject to a CDSC
at the rates set forth below. This charge will be assessed on an amount equal to
the lesser of the current market value or the original purchase cost of the
shares being redeemed. Accordingly, you will not be assessed a CDSC on increases
in account value above the initial purchase price, including shares derived from
dividend reinvestments.

In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
It will be assumed that your redemption comes first from shares you have held
beyond the six-year CDSC redemption period or those you acquired through
dividend reinvestment, and next from the shares you have held the longest during
the six-year period. The CDSC is waived on redemptions in certain circumstances.
See the discussion "Waiver of Contingent Deferred Sales Charges" below.

EXAMPLE:

You have purchased 100 shares at $10 per share. The second year after your
purchase, your investment's net asset value per share has increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment. If
you redeem 50 shares at this time, your CDSC will be calculated as follows:

* Proceeds of 50 shares redeemed at $12 per share                      $ 600
* Minus proceeds of 10 shares not subject to CDSC because they were
  acquired through dividend reinvestment (10 x $12)                     -120
* Minus appreciation on remaining shares, also not subject to CDSC
  (40  x $2)                                                            - 80
* Amount subject to CDSC                                               $ 400

Proceeds from the CDSC are paid to John Hancock Funds. John Hancock Funds uses
all or part of them to defray its expenses related to providing the Fund with
distribution services connected to the sale of the Class B shares, such as
compensating selected Selling Brokers for selling these shares. The combination
of the CDSC and the distribution and service fees makes it possible for the Fund
to sell Class B shares without deducting a sales charge at the time of the
purchase.

The amount of the CDSC, if any, will vary depending on the number of years from

<PAGE>   18

the time you purchase your Class B shares until the time you redeem them. Solely
for purposes of determining the holding period, any payments you make during the
month will be aggregated and deemed to have been made on the last day of the
month.

</TABLE>

A commission equal to 3.75% of the amount invested and a first year's service
fee equal to 0.25% of the amount invested, are paid to Selling Brokers. The
initial service fee is paid in advance at the time of sale for personal and
account maintenance services provided to shareholders during the twelve months
following the sale. Thereafter the service fee is paid in arrears.

UNDER CERTAIN CIRCUMSTANCES, THE CDSC ON CLASS B AND CERTAIN CLASS A SHARE
REDEMPTIONS WILL BE WAIVED.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES. The CDSC will be waived on
redemptions of Class B shares and of Class A shares that are subject to a CDSC,
unless indicated otherwise, in the circumstances defined below:

* Redemptions of Class B shares made under a Systematic Withdrawal Plan (see
  "How to Redeem Shares"), as long as your annual redemptions do not exceed 10%
  of your account value at the time you established your Systematic Withdrawal
  Plan and 10% of your value of subsequent investments (less redemptions) in
  that account at the time you notify Investor Services. This waiver does not
  apply to Systematic Withdrawal Plan redemptions of Class A shares that are
  subject to a CDSC.

* Redemptions due to death or disability.

* Redemptions made under the Reinvestment Privilege, as described in "Additional
  Services and Programs" of the Prospectus.

* Redemptions made pursuant to the Fund's right to liquidate your account if you
  own fewer than 50 shares.

* Redemptions made in connection with certain liquidation, merger or acquisition
  transactions involving other investment companies or personal holding
  companies.

* Redemptions from certain IRA and retirement plans that purchased shares prior
  to October 1, 1992.

If you qualify for a CDSC waiver under one of these situations, you must notify
Investor Services either directly or through your Selling Broker at the time you
make your redemption. The waiver will be granted once Investor Services has
confirmed that you are entitled to the waiver.

CONVERSION OF CLASS B SHARES. Your Class B shares, and an appropriate portion of
reinvested dividends on those shares, will be converted into Class A shares
automatically. This will occur at the end of the month eight years after the
shares were purchased, and will result in lower annual distribution fees. If you
exchanged Class B shares into this Fund from another John Hancock fund, the
calculation will be based on the time you purchased the shares in the original
fund. The Fund has been advised that the conversion of Class B shares to Class A
shares should not be taxable for Federal income tax purposes, nor should it
change your tax basis or tax holding period for the converted shares.

HOW TO REDEEM SHARES

You may redeem all or a portion of your shares on any business day. Your shares
will be redeemed at the next NAV calculated after your redemption request is
received in good order by Investor Services, less any applicable CDSC. The Fund

<PAGE>   19

may hold payment until it is reasonably satisfied that investments recently made
by check or Invest-by-Phone have been collected (which may take up to 10
calendar days).

Once your shares are redeemed, the Fund generally sends you payment on the next
business day. When you redeem your shares, you may realize a taxable gain or
loss depending usually on the difference between what you paid for them and what
you receive for them, subject to certain tax rules. Under unusual circumstances,
the Fund may suspend redemptions or postpone payment for up to seven days or
longer, as permitted by Federal securities laws.

                       days on which the New York Stock Exchange is closed.
                       Investor Services employs the following procedures to
                       confirm that instructions received by telephone are
                       genuine.  Your name, the account number, taxpayer
                       identification number applicable to the account and other
                       relevant information may be requested.  In addition,
                       telephone instructions are recorded.
                       You may redeem up to $100,000 by telephone, but the
                       address on the account must not have changed for the last
                       30 days. A check will be mailed to the exact name(s) and
                       address shown on the account.
                       If reasonable procedures, such as those described above,
                       are not followed, the Fund may be liable for any loss due
                       to unauthorized or fraudulent telephone instructions.  In
                       all other cases, neither the Fund nor Investor Services
                       will be liable for any loss or expense for acting upon
                       telephone instructions made in accordance with the
                       telephone transaction procedures mentioned above.
                       Telephone redemption is not available for shares of the
                       Fund that are in certificate form.
                       During periods of extreme economic conditions or market
                       changes, telephone requests may be difficult to implement
                       due to a large volume of calls.  During these times you
                       should consider placing redemption requests in writing or
                       using EASI-Line.  EASI-Line's telephone number is

  Funds may guarantee the signature. The following institutions may provide you
  with a signature guarantee, provided that the institution meets credit
  standards established by Investor Services: (i) a bank; (ii) a securities
  broker or dealer, including a government or municipal securities broker or
  dealer, that is a member of a clearing corporation or meets certain net
  capital requirements; (iii) a credit union having authority to issue signature
  guarantees; (iv) a savings and loan association, a building and loan
  association, a cooperative bank, a federal savings bank or association; or (v)
  a national securities exchange, a registered securities exchange or a clearing
  agency.

  THROUGH YOUR BROKER  Your broker may be able to initiate the redemption.
                        Contact your broker for instructions.
- ------------------------------------------------------------------------------
  If you have certificates for your shares, you must submit them with your stock
  power or a letter of instruction. Unless you specify to the contrary, any
  outstanding Class A shares will be redeemed before Class B shares. You may not
  redeem certificated shares by telephone.

- ------------------------------------------------------------------------------

ADDITIONAL INFORMATION ABOUT REDEMPTIONS

  Due to the proportionately high cost of maintaining smaller accounts, the Fund
  reserves the redeem at net asset value all shares in an account which holds
  fewer than 50 shares (except accounts under retirement plans) and to mail the
  proceeds to the shareholder, or the transfer agent may impose an annual fee of
  $10.00. No account will be involuntarily redeemed or additional fee imposed,
  if the value of the account is in excess of the Fund's minimum initial
  investment. No CDSC will be imposed on involuntary redemptions of shares.


<PAGE>   21
  Shareholders will be notified before these redemptions are to be made or this
  fee is imposed, and will have 30 days to purchase additional shares to bring
  their account balance up to the required minimum. Unless the number of shares
  acquired by further purchases and dividend reinvestments, if any, exceeds the
  number of shares redeemed, repeated redemptions from a small account may
  eventually trigger this policy.

ADDITIONAL SERVICES AND PROGRAMS

EXCHANGE PRIVILEGE


YOU MAY EXCHANGE SHARES OF THE FUND FOR SHARES OF THE SAME CLASS OF ANOTHER JOHN
HANCOCK FUND.

If your investment objective changes, or if you wish to achieve further
diversification, John Hancock offers other funds with a wide range of investment
goals. Contact your registered representative or Selling Broker and request a
prospectus for the John Hancock funds that interest you. Read the prospectus
carefully before exchanging your shares. You can exchange shares of each class
of the Fund only for shares of the same class of another John Hancock fund. For
this purpose, John Hancock funds with only one class of shares will be treated
as Class A, whether or not they have been so designated.

Exchanges between funds that are not subject to a CDSC are based on their
respective net asset values. No sales charge or transaction charge is imposed.
Class B shares of the Fund that are subject to a CDSC may be exchanged for Class
B shares of another John Hancock fund without incurring the CDSC; however these
shares will be subject to the CDSC schedule of the shares acquired (except that
exchanges into John Hancock Short-Term Strategic Income Fund, John Hancock
Adjustable U.S. Government Trust and John Hancock Limited-Term Government Fund
will be subject to the initial fund's CDSC). For purposes of computing the CDSC
payable upon redemption of shares acquired in an exchange, the holding period of
the original shares is added to the holding period of the shares acquired in an
exchange. However, if you exchange Class B shares purchased prior to January 1,
1994 for Class B shares of any other John Hancock fund, you will continue to be
subject to the CDSC schedule that was in effect at your initial purchase date.

You may exchange Class B shares of any John Hancock fund into shares of a John
Hancock money market fund at net asset value. However, you will continue to be
subject to a CDSC upon redemption. The rate of the CDSC will be the rate in
effect on the original fund at the time of the exchange.

The Fund reserves the right to require that you keep previously exchanged shares
(and reinvested dividends) in the Fund for 90 days before you are permitted to
execute a new exchange. The Fund may also alter the terms of or terminate the
exchange privilege upon 60 days' notice to shareholders.

An exchange of shares is treated as a redemption of shares of one fund and the
purchase of shares in another for Federal income tax purposes, and may result in
a taxable gain or loss.

When you make an exchange, your account registration in both the existing and
new account must be identical. The exchange privilege is available only in
states where the exchange can be made legally.

Under exchange agreements with John Hancock Funds, certain dealers, brokers and
investment advisers may exchange their clients' Fund shares, subject to the
terms of those agreements and John Hancock Funds' right to reject or suspend
those exchanges at any time. Because of the restrictions and procedures under
those agreements, the exchanges may be subject to timing limitations and other
restrictions that do not apply to exchanges requested by shareholders directly,
as described above.

Because Fund performance and shareholders can be hurt by excessive trading, the
Fund reserves the right to terminate the exchange privilege for any person or
group that, in John Hancock Funds' judgment, is involved in a pattern of
exchanges that coincide with a "market timing" strategy that may disrupt the
Fund's ability to invest effectively according to its investment objective and
policies, or might otherwise affect the Fund and its shareholders adversely. The
Fund may also temporarily or permanently terminate the exchange privilege for
any person who makes seven or more exchanges out of the Fund per calendar year.

<PAGE>   22
Accounts under common control or ownership will be aggregated for this purpose.
Although the Fund will attempt to give you prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time.

BY TELEPHONE

1. When you fill out the application for your purchase of Fund shares, you
   automatically authorize exchanges by telephone unless you check the box
   indicating that you do not wish to have the telephone exchange privilege.

2. Call 1-800-225-5291. Have the account number of your current fund and the
   exact name in which it is registered available to give to the telephone
   representative.

3. Your name, the account number, taxpayer identification number applicable to
   the account and other relevant information may be requested. In addition,
   telephone instructions are recorded.

IN WRITING

1. In a letter, request an exchange and list the following:
  -- the name and class of the fund whose shares you currently own
  -- your account number
  -- the name(s) in which the account is registered
  -- the name of the fund in which you wish your exchange to be invested
  -- the number of shares, all shares or the dollar amount you wish to exchange

Sign your request exactly as the account is registered.

2. Mail the request and information to:
     John Hancock Investor Services Corporation
     P.O. Box 9116
     Boston, Massachusetts 02205-9116

REINVESTMENT PRIVILEGE

IF YOU REDEEM SHARES OF THE FUND, YOU MAY BE ABLE TO REINVEST THE PROCEEDS IN
THE FUND OR ANOTHER JOHN HANCOCK FUND WITHOUT PAYING AN ADDITIONAL SALES CHARGE.

1. You will not be subject to a sales charge on Class A shares that you reinvest
   in any John Hancock fund that is otherwise subject to a sales charge, as long
   as you reinvest within 120 days from the redemption date. If you paid a CDSC
   upon a redemption, you may reinvest at net asset value in the same class of
   shares from which you redeemed within 120 days. Your account will be credited
   with the amount of the CDSC previously charged, and the reinvested shares
   will continue to be subject to a CDSC. For purposes of computing the CDSC
   payable upon a subsequent redemption, the holding period of the shares
   acquired through reinvestment will include the holding period of the redeemed
   shares.

2. Any portion of your redemption may be reinvested in the Fund shares or in
   shares of any of the other John Hancock funds, subject to the minimum
   investment limit of that fund.

3. To reinvest in shares of the Fund, you must notify Investor Services in
   writing. Include the Fund(s) name, account number and class from which your
   shares were originally redeemed.

SYSTEMATIC WITHDRAWAL PLAN

YOU CAN PAY ROUTINE BILLS OR MAKE PERIODIC DISBURSEMENTS FROM YOUR ACCOUNT.

1. You can elect the Systematic Withdrawal Plan at any time by completing the
   Account Privileges Application which is attached to this Prospectus. You can
<PAGE>   23

   also obtain the Application from your registered representative or by calling
   1-800-225-5291.

2. To be eligible, you must have at least $5,000 in your account.

3. Payments from your account can be made monthly, quarterly, semi-annually or
   annually or on a selected monthly basis to yourself or any other designated
   payee.

4. There is no limit on the number of payees you may authorize, but all payments
   must be made at the same time or intervals.

5. It is not advantageous to maintain a systematic withdrawal plan concurrently
   with purchases of additional Class A or Class B shares because you may be
   subject to an initial sales charge on your purchases of Class A shares or to
   a CDSC on your redemptions of Class B shares. In addition, your redemptions
   are taxable events.

6. Redemptions will be discontinued if the U.S. Postal Service cannot deliver
   your checks, or if deposits to a bank account are returned for any reason.

MONTHLY AUTOMATIC ACCUMULATION PROGRAM (MAAP)

YOU CAN MAKE AUTOMATIC INVESTMENTS AND SIMPLIFY YOUR INVESTING.

1. You can authorize an investment to be drawn automatically each month from
   your bank for investment in Fund shares, under the "Automatic Investing" and
   "Bank Information" sections of the Account Privileges Application.

2. You can also authorize automatic investing through payroll deduction by
   completing the "Direct Deposit Investing" section of the Account Privileges
   Application.

3. You can terminate your Monthly Automatic Accumulation Program at any time.

4. There is no charge to you for this program, and there is no cost to the Fund.

5. If you have payments being withdrawn from a bank account and we are notified
   that the account has been closed, your withdrawals will be discontinued.

GROUP INVESTMENT PROGRAM

ORGANIZED GROUPS OF AT LEAST FOUR PERSONS MAY ESTABLISH ACCOUNTS.

1. An individual account will be established for each participant, but the
   initial sales charge for Class A shares will be based on the aggregate dollar
   amount of all participants' investments. To determine how to qualify for this
   program, contact your registered representative or call 1-800-225- 5291.

2. The initial aggregate investment of all participants in the group must be at
   least $250.

3. There is no additional charge for program. There is no obligation to make
   investments beyond the minimum, and you may terminate the program at any
   time.
